content: Hello everyone,There is little documentation on how to use TE Q1 for image processing so I must ask my question here even though I'm not sure about wether or not this is the appropriate forum.So I acquired a TE Q1 camera yesterday and what i'm interested in doing is to plot some graphs of the temperature an object in time (so like a picture every 10 minutes for 2 hours then I plot the data).From what I can understand, the .csv files open in excel sheet and each 'excel square' has the temperature of one pixel, which is great cause that's exactly what I want, a document which contains the temperature of every pixel. However, this only happens with their own images. More precisely, when you download their TE analysis program, they offer you some examples of the pictures they've taken as well as their associated .csv files that you can play around with.When I take a picture (and I save the picture under the thermal, temperature and temprature option) the .csv that I receive just shows infinity for every pixel. At the same time, I also cant open my picture with their analysis program because they say something like the .csv file doesn't exist. However, I'm going to to try that out with Joe's thermal analysis program to see if I have more luck there.Has anybody in here ever had this problem and what was your solution for it?Thank you so much!

content: Ok I ''figured it out''. So to not have infinity and instead actual temperatures in your .csv files, you need to set the emissivity to whatever value other than zero (/facepalm).To load the picture in the thermal expert analysis program, you need to have these three files in the same folder: the IR picture, the VIS picture and the .csv document. On the Samsung Galaxy s5 that I'm using, I can’t import these three formats at the same time. More precisely, when I plug in the phone on my computer, I'm asked about what kind of files I want to transfer to the computer. I had the choose the option ''transfer images'' to get the IR and VIS picture files and then I had to choose ''transfer media files'' to get the .csv file to the computer and voilà!Perhaps the way to transfer files from phone to computer varies considerably from the type of phone you're using so this advice may not be useful for everyone who happens to be in a similar predicament, but hopefully it will be pertinent to some of you!Good day

content: Hey that's my picture!I have no idea where you might find one other than asking Seek or someone who removed theirs & doesn't want it anymore. BUT consider this: If you lost the pin you have also likely lost the reference point of where the lens was able to focus while the pin was installed & you might not be able to get it back in the right place. The pin restricted the focus adjustment to one turn. But how far out was the lens when you removed the pin?My experience is that removing the pin allowed the lens to move out one more turn. So if you are having trouble focusing without that pin in there, try this:Turn the lens shroud fully counter-clockwise (not forcing it), then you will have it on very close focus. And about 2 turns clockwise from there should get you focused on distant objects. It has 2 or 3 more turns to go at that point before it hits bottom and if you go into that range you will just be more out of focus.Another thing, is the pin actually lost or is it just pushed up inside the shroud?

content: If you screw the shroud counterclockwise to the point that the lens is pushing against the top of the shroud you can more easily slip tweezers between the bottom of the shroud and the camera lid to pry out the little tabs that hold the shroud to the bayonet mount & pop the shroud off. OR if you have the lid off the camera you could screw the bayonet mount off the lid & then you could easily get at those tabs & pry the shroud off. You would still have to figure out how to get the lens at the right point on the threads and put the shroud back on in the right orientation to get your desired focal range with the blocking pin in place.

Reflected temperature with Thermal Expert Q1 - Page 1
Forum section: electronics / general

timestamp: May 21, 2018, 02:08:25 pm
content: Hello everyone!From what I understand, reflected temperature correction is the correction that you need to input in a thermal imaging device in order to remove the background radiation. I've noticed that Fluke has a setting for reflected temperature correction and most people suggest using an aluminum foil has a corrector since it has a considerable low emissivity.However, I don’t have the Fluke camera but rather the Thermal Expert Q1 and I can’t find any reflected temperature setting when I go through the TE settings. Does anybody know why that's the case? Does TE just simply automatically correct background radiation?Thank you so much!

content: So, I lucked into an MS224b, and I started off using the Razor EOL tool package w. modified firmware . dfu to get added color palettes, and a variety of other (seemingly unstable) options. It took a few tries to get it installed and working with the correct brightness, but finally got it installed and working decently. Now: I was wondering if there was a better firmware that would make it easier to program the scenes, and increase clarity of the image, as well as record via the USB output instead of the hot shoe (which I destroyed somehow). I am very new to this so please be patient if at all possible.Thank you so much... I feel like I am missing a lot, but it is hard to pore through all the info on this pretty deep forum.

content: As no one else has responded, I will comment.For a newbie, you have been very adventurous with your thermal scope !The modified firmware was developed using what could best be described as a risky process. It was the result of one persons differential analysis of the FLIR Scout scope firmware and that of a FLIR based thermal vision rifle scope. The firmware of the Scout was then modified to contain additional elements from the rifle scope version without a full understanding of the changes. Such an approach is risky and as the firmware is not understood, it can be difficult to rectify issues. It is classed as blind hacking of firmware in my world and very risky. This is why your firmware does not behave perfectly and some functions appear unstable.The other issue with this approach to firmware modification is that it can be very difficult, or even impossible to revert to the stock (stable) firmware.The SCOUT firmware and configuration has not been reverse engineered and cannot be manipulated as easily as that in the E4 camera. The modified firmware that you have used is the only one known to me and I chose not to use it due to its risky development process. If you kill the firmware on a Scout through an incorrect change, you can render the unit useless, requiring return to FLIR for a Firmware reload. Be careful if you decide to change anything in that hybrid firmware that you are running. Some might call that 'hacked' firmware a kind of Frankensteine's Monster of firmwares. The result of grafting different versions together.The Video output on the USB socket was standard on the Scout II series so I would have expected it to be present on your unit if it is a series II chassis inside. It is a hardware difference to the MK1 Scout scope that only outputs video from the base contact.Fraser

content: I bought a Flir thermal camera and still learn how to use it.I would like to use it for reparing electronic devices. Recently I tried to repair a mobile( old Nokia 6303) that had a short circuit( when connected to a power supply it drew some current).So I used a camera and found out CPU had the highest temperature among all other items. I thought that CPU is the culprit.But generally CPU is powered from PMIC( Power managment IC).Does it mean that PMIC( Power managment IC) supplies higher current becauseCPU is faulty(shorted)orPMIC( Power managment IC) is faultybut designed for a higher current so the temperature is lower than CPU?Where would you search the short first? Would you replace PMIC( Power managment IC) first or CPU? Or any cappacitor?Thanks for your suggestions

timestamp: May 06, 2018, 03:32:52 am
content: If you expect the normal operating temperature of the CPU to be much lower than 45C, then the CPU is probably a culprit. You can try measuring the voltage and resistance on the power pins of the CPU to make sure it is being supplied the right voltage and that it's not shorted through the CPU. If voltages aren't correct, then there's probably a problem with the PSU and/or PMIC as well, and it wouldn't rule out the CPU being damaged. You have to use the other tools at your disposal, not just the thermal camera. Use all the info available and make some inferences as to which components are damaged.

Does it also output the calibration data needed to calculate an actual temperature values (like degrees F)? Also, can a command be sent to it to get it to output a signal that is proportional to the sensor's voltage? Or for that would you need to downgrade to the 3.0 Lepton?

content: Quote from: Ben321 on April 09, 2018, 11:30:45 amThe pixel value is directly related to the temperature, usually some mK per count. No calibration data needed, though you can compensate for atmospheric temps and whatnot.You can also disable radiometry and do AGC like on any other Lepton. Just look at the datasheet, it should be fairly clear.

I play to go there tommorow or Friday and have a look.But there are some questions I couldn't find answers to:Can you disable DDE?When recording video, how bad is it compressed and does it change pallette range?It says fixed focus, but would you be physical able to change something like for Ex cameras?Any idea about firmware hacks for it?Are the optics coated Ge or other? Could you use them for other Lepton based projects?Does it's battery degrade over time and can you replace it?I will ask those questions the experts in the flir store, but I would love to know if anyone had any hand on experience with it.

The lens or product manufacturer should specify what solutions are safe to use and what not to use. If you don't KNOW how to properly clean a lend then go get some expert advice. If your idea of cleaning is just rubbing a lens to clean it then I'll just tell that you can ruin a lens the first time that do that. Especially if the lens is uncoated Germanium.

FLIR recommend that cleaning only be undertaken if the lens is heavily contaminated. They further recommend that external thermal CCTV lenses are best left alone and no wiper used to clean the window. Their tests proved cleaning was rarely needed.Fraser

content: So i have been looking through the internet again and found some retailers that also have thermal cameras. They sell their demo units as used but with limited warranty. I actually drove to visit such a retailer to day, as it was a bike trip to the next town on a wonderful spring day, but found it closed on a Saturday.And just now I found this:https://vermex.de/Gebrauchtgeraete/Thermografie-83/Flir-T460-Waermebildkamera-mit-3-Optiken.htmlSo they offer a demo unit FLIR T460 with 3 lens options for 5.500€. This seems too good to be true. As the lenses itself cost a lot. I was wondering if the T400 lenses can be used on newer Flir cameras - but there seems to be no information on that available at the surface.

content: These are converters/adapters - they can only be used on top of existing built-in(non-removable) lenses, so any FLIR Ex and Exx camera, as well as the T4xx and earlier, will work(with DIY mechanical adapters). The T6xx cameras use newer, differently-mounted lenses.However, the lenses themselves contain calibration data and an integrated temperature sensor, which is crucial to temperature measurement due to the rather sloppy performance of Germanium over different temperatures, as well as having an additional emitting optical element(remember, above 0K) in the optical path.I suspect they're either I2C or SPI, so it should be fairly easy to read out.

But no official word on resolution. They said the visible resolution for the MSX image improved. And high temperature range.The air sensor is really interesting. I wonder if it only detects some solvents and toxic fumes... Or if you can use it as gas spectrometer, which would be really cooldown for chemistry.Laser for distance measurements on photos sounds interesting.I won't upgrade, as is 900€ and my CAT S60 still works.Still better then a C3 by far.

content: Hi,I'm designing a thermal camera using a sensor from ULIS which outputs an analog signal output which needs to be processed inorder to obtain the image. Please check the attachment for the waveform output.I'm thinking of using a CCD sensor Analog Front End likehttp://www.ti.com/product/VSP5611. Are there any problem in using a CCD sensor AFE for this a non-CCD sensor, taking into consideration that the output doesn't have a waveform expected from a CCD sensor. Also the AFE has an input of 2V and the sensor output swings between 0.5V and 2.9V. Other than using a simple resistor divider, is there any other better methods for scaling down the signal considering aspects like signal integrity etc.. What about a difference amplifier as shown here to achieve a gain less than unity?http://hyperphysics.phy-astr.gsu.edu/hbase/Electronic/opampvar6.html

Pinhole lens for thermal camera - Page 1

content: So I thought about lens options again. Germanium and even ZnSe aren't very accessible for me so I resulted to different techniques. Mirrors were one option but highly complicated and in need for high quality.Pinhole lenses has been the cheap toy to cameras for a while. In theory they should work.A quick search has thrown that someone build a pinhole scanner.My concerns are that pinholes have a really replay tiny Aperture and therefore need a lot my light coming in. I don't know alot about exposure theory in thermal cameras tho and how much exposure time matters.My plan is to read up on the topic and use a pinhole calculator to see what could be achieved. Then 3d model and print a lens bracket and use paper or thin Metalsheet for the pinhole.Has anyone tried this stuff?

content: I haven't tried this, but intuitively I don't think it will work for the sort of uncooled LWIR sensors we all know and love because you simply won't get enough thermal radiation through such a small hole.A typical-sensitivity uncooled LWIR sensor lens system is about f/1 to f/1.4 and a high-sensitivity cooled (probably MWIR) system will have an aperture of somewhere in the region off/4 orf/5. Pinholes tend to have averyhighf/ number - think in terms off/100 orf/200. I suspect there will be so little thermal radiation reaching the sensor through a pinhole lens that you're very unlikely to see anything other than the very hottest targets - maybe the sun, if you're lucky.Even a modern DSLR might need an exposure measured in seconds when using a pinhole lens, and they are many orders of magnitude more sensitive than thermal imagers.As an aside, has anyone ever tried to calculate the equivalent ISO sensitivity of a thermal camera?

There are a few detectors that operate in the LWIR microbolometer spectrum.Specifically WISE at 10micron for example. There are only a few ground based telescopes with infrared detectors in the 8-14nm spectrum, but it is possible due to the window being between 5 and 9.but the topic here is black paint emissivity. I guess you want the best possible ratio of least reflection and pure emission of IR radiation? Is paint really the best option or could you go for some material?Can you read up on what airports use for their blackbody reference on fever screening?

timestamp: February 06, 2018, 01:52:50 pm
content: The BB references at airports are small versions of the standard camera calibration charts, generally 0.99 or better emissivity.See products from the likes of CI systems, HGH Infrared, SBIR etc. and on these the surfaces are often micromachined as well as painted. That effectively gives you a load of tiny cavities.For high temperatures a cavity works well, so you have the 'BB-4' from Omega and similar. In this case the cavity is white ceramic and can go up to 1000°C, about 1 inch diameter.An 8 " 500°C source is rather uncomfortable to be near. Definitely no nylon or chocolate allowed nearby.Bill

My initial instructions were to, "...delete the corresponding camera serial number folder under ThermApp, and then the phone connected to the network, use the ThermViewer download the file and activate the license." I copied the file titled with my Therm-App serial number from my LG G4 and saved it to a PC rather than deleting it. Then I deleted it from my LG G4. Next I ran Thermviewer. My phone connected to the server and downloaded a configuration file but no license. I contacted Jinhua again and received more detailed instructions which were, "The specific way of operation is to open the "ThermApp/2456240**" folder in the cell phone, delete the "FilesList.json" file and run the "ThermViewer" APP. The APP automatically downloads the corresponding configuration files to activate the license." There are two files listed in my phone so I started by deleting "FilesList.json" and repeated the download process to no avail. Next I deleted "FilesList2.json" and repeated the process to no avail. Next I deleted both files to no avail. Perhaps there is a setting I have to switch as I did for the OEM app to function or Perhaps not. Any ideas?Thanks,Mike
