content: Hello,in our small software company we'd like to start with hardware development and started to build some hardware prototypes. These will be more or less embedded PC's in custom enclosure with our I/O PCB - so no "heavy" PCB development here.Nontheless we'd like to see the thermal dissipation and thermal propagation of the prototypes in idle and under load and find hotspots. For that we need a thermal camera. The measurements will be done in room conditions.I have read here several threads on starter (~500€) cameras and came to the conclusion to take one from Hikmicro, because we will need a PC software to analyze the data and they seem to be the only brand in that price category to provide analysis soft for PC.We'd like to Analyse the PCBs and the assembly by making several images over time and get temperatures on different spots. Video option is cool, but not necessary.So I see three options for now:- B10 (480€)- B20 (555€)- Pocket2 (575€)Once we have a camera, we'll print an enclosure and attach ZnSe lens for additional macro option.All of the above cameras have a decent sensor. As I read, some have better image processing etc.Which one would fit the purpose and is the extra money worth to buy a B20 or Pocket2? Or are there no extra benefits for this use case and B10 would do the job?Thank you

content: Its an old post but I would like to add the following, although you've probably already decided which one to take:B20 = handheld thermal cameraPocket 2 = cooler chassis + higher resolution of the screen + touch gestures (same screen like the M-Series of hikmicro)B10 = same as B20 but without WLAN (so no ability to record videos or transfer files via WLAN).If you use keepa.com you can find the best prices on Amazon. B10 is 350 € sometimes, B20 520€.
Indigo Core from MSA Evolution 5200, stuck shutter? - Page 1

content: G'day.I bought a defective MSA Evolution 5200 from Ebay. Description said, image stays gray most of the times.Had this issue before with a IIG thermal imager, freed the shutter and it just worked fine.I tested the MSA, and whenever I switch it on, the shutter seems to be stuck, when I hit the unit, image comes up. Sometimes the shutter "wants" to close, and freezes the given image, so there is a "ghost image", hope you know what I mean...I disassambled the MSA today, but can't find a way to the shutter. A label on the side of the unit says "Indigo Core", I found some info on the indigo cores, but I am pretty sure, disassembly to the shutter motor is very delicate...Maybe some of you have a good idea?Best regardsHenning

content: Hi, i've come across a thermal imaging module from from an ex-army auction.I believe it was manufactured by Thales, and it was installed to a Stryker as part of the Protector RWS package.I've been able to find out that its video output is NTSC, and it communicates via a RS422/RS485 transceiver (MAX3490), which I believe is connected to one of the pads on the underside of the Altera FPGA.In the linked video you can see it powering on, going through its focus cycle and stopping. I have been unable to figure out what protocol can be used to communicate with it over the serial line.Does anyone have any information that might help me figure this out?I've gone to the effort of extracting the flash to see if i can figure anything out, but there's really nothing in there that helps me in any way.Does anyone have any information that might help me? for example, information regarding the "TIM family interface"?I've had a few theories about it being controlled by MODBUS, or some PTZ camera protocol, but i've not really had any luck.The camera never seems to send any responses, nor emit anything over its serial line.*https://streamable.com/h2u8y7*https://en.wikipedia.org/wiki/Protector_RWS*https://www.thalesgroup.com/en/worldwide/defence/tim-tactical-range-thermal-imagers*https://www.thalesgroup.com/sites/default/files/database/d7/asset/document/tim-tr_dfov_datasheet.pdf*https://www.analog.com/en/products/max3490.html

If I buy a camera with USB-C now (February 2023), will it work with the USB-C-iPhones? (Of course, the item description of the camera with USB-C does not say anything about iPhones at the moment).2. You should not only be able to operate these cameras on a mobile phone as a display, but also with the PC as a screen using the "Thermovision" software, completely without a mobile phone.Does anyone know whether the USB-C or Lightning variant would be better suited for this?I would be very happy to hear your thoughts on this.Thanks in advance.

content: Connecting it to a PC should be safe, there is no difference between USB ports on a PC and a phone.But bridging it to the emulator may not be possible.There is a chance that it is a standard UVC class device and you would be able to open it in the regular camera applications. But even if that's the case, you won't have any controls.It might be easier to get a cheap second hand phone. It does not need to be anything fancy to run one app.

Does emissivity affect to calibration curves? - Page 1

content: Good afternoon,I would like to know if changing the emissivity affects somehow to the shape/slope of the calibration curve of the camera.The question comes from the following doubt:If I measure at two different times a relative temperature difference at one point of 20º with an emmisivity X. If I change the emissivity for the same thermal video, will this relative diference change for the same time period?Thank you

timestamp: October 07, 2023, 01:02:50 pm
content: Not sure what you mean with the calibration curves but to get correct temperature difference between object A and B you need to use correct emissivity value.If both objects are at relatively high temperature the the emissivity setting has minor effect on relative difference.If one object is at room temperature(background radiation temperature) and another is lot hotter the emissivity setting has huge effect on displayed temperature difference.

Initial idea was to purchase Flir VPC module for it, but then I discovered that you take analog video signal directly from 50-pin hirose connector (the white on on the back of the camera), so purchasing this VPC module would be a waste of money.Ok, just add some CVBS to USB video grabber to it and mission complete, but then I came across Tau 2 Electrical Interface Description Document (attached) which explains digital (CMOS and LVDS) video formats that camera can spit out.I was struggling to find any LVDS interface, but there is plenty of CMOS->USB modules on the market - like those that you can pair with i.eg. OV2640 CMOS cameras.Have anybody of you ever tried to grab digital signal instead of analog one from Tau 2?Would the digital video transmission benefit in any way an image quality?

But when it comes to radiometric calibration up to 150°C partial field of view exposure in 2m distance i see the blackbody afterwards persistent in the image.Can someone tell me if it is it necessary to expose the factory new sensor to "high" flux before calibration (burnin?)?Best regardssoyd

content: Never heard of that being of any use.How long does the remnant image stay there ?If you are back to a blank scene and with high gain you are likely to see some remnant image. This is because you will have heated up the pixel structures (not just the sensing part) to some extent with the 150°C so you can get some after effects as things cool back down again. That is both 'live' effects and that effect stored by any FFC calibration.Bill

content: The pattern is persistent since about 36 hours.The sensor is set to lowest possible gain. I already calculated a calibration with a scene temperature range of 10-60°C. With this calibration this comes out to ~0,3°C higher temperature at the remnant over the hole temperature range. At least it still shows linear behaviour just with a little offset change.It`s an uncooled shutterless approach, so there`s no live FFC. The correction routine was already tested with an PICO sensor, where radiometric calibration up to 150°C was done over full FOV of the sensor at only 25cm distance. Afterwards even looking for hours at a hot scene in 2m distance no such remnants were permanently visible.Now i changed my teststand for radiometric calibration to 2m distance and only a part of the image is covered by the blackbody. The only difference i see is that i don`t exposure the whole sensor to high flux.Some gray hairs more...

People have asked where to buy these previously and now they will knowA 3D printed casing does make life easier when it comes to mounting the connector on the top. Even just a top cap that holds the connector securely to the battery would work well. You solution using hot melt glue works though and that is what mattersAnother option might be to make a simple Plasticene (children’s modelling clay) mould for a top cap that will hold the contacts and pour either 2 part Epoxy glue of plastic embedding resin into it to make a moulded part. An original battery can be used to make the basis of mould by pushing it into the modelling clay (with the contact holes covered) Hours of fun to be had

content: If I am not mistaken Merlin had 3 cameras. NIR, MWIR, LWIR They all had the same body. I had one once (LWIR uncooled) but I no longer own it. Apparently the MWIR used a linear cooler. So buying one second hand isn't a bad idea (My amber radiance is much older and still works!). They tend to have great cool down times (5-6min). The interface is a bit dated and the connectivity isn't the friendliest. I believe it worked with FLIR researcher (not sure tho) I attached the datasheet for more info on the 3 cameras in their line.

content: Same here. Work had three of the LW's and one of the Vis/NIR. They were excellent for their day. Worked with custom collection software and also RTools. Never used a MW as we had Amber's of older vintage but better focal planes.Reason I add the Vis part is the sensor had a enough of a response that if you used a blocking filter on the NIR then it could see in the visible.

content: This might be amusing to some of you other old-timers :-)I recently stumbled across an ESP32 library (https://github.com/aquaticus/esp32_composite_video_lib) that uses the built-in DAC and I2S peripheral to create a PAL or NTSC (or SECAM) analog video output (monochrome only). I thought that was pretty cool and it inspired me to make a mash-up of it with my own thermal imaging camera firmware to create an analog output camera. I think the output looks a lot like some of the photos Fraser posts from older camera.The first pic below is a home-built version of the camera imaging some black-body radiators.The hardware is my own tCam-Mini design or you can build your own if you have an ESP32 with WROVER module and a Lepton breakout board. It works with all 160x120 pixel Lepton 3.X modules (including the new 90° 3.1R). It can display a spotmeter temp (with old-school 7-segment temp reading) and minimum/maximum point markers and has a whole two palettes (white-hot, black-hot).You can even set the emissivity and temperature units (C or F). The doc and firmware is athttps://github.com/danjulio/tCamMiniAnalogin case anyone cares to take a look.I'll probably make a version for the Infiray Tiny1-C core as well at some point. I think I should be able to get 18-20 FPS from that little beastie.

The problem always was that the app very often launched with mirrored/flipped camera image.I downloaded InfiCam app from discord. Then, the problem is there is noise visible in the image. Xtherm has nice smooth image, Inficam noisy. Can something be done about the noise in InfiCam?Or is there an app that really works with T2S+ - i.e. it doesn't mirror/flip image from the camera randomly and doesn't produce noisy image?

Uses for NIR imaging?  Nabbed an old Find-R-Scope at auction. - Page 1

I do the resale thing with various stuff including electronics bench equipment, so I end up going to auctions for industrial electronics and such.I picked up an old model Find-R-Scope for super-cheap, about $80. I mostly bid on it last minute after looking up sold models on eBay and seeing they went for up to $800.Anyway, it works perfectly and has a sensitivity range from 350nm (just barely up into UV range) to ~1350nm (it's mostly for NIR) (I'm told that with age the lower edge of the spectrum sensitivity tends to drop off slightly) and I'm wondering - is this a useful piece of equipment that I should keep for my lab bench?I already have a thermal camera, so I don't need it for detecting hot spots / overheat failures on boards - and it's not particularly good at picking up thermal IR anyway since that's in the 1,000nm to 14,000nm range anyway - so, before I put it in the 'sell it' pile, are there uses for this in a hobbyist electronics lab that I should be aware of?I have this bad habit of wanting to keep it just because it's a cool and somewhat rare bit of kit (TEA syndrome there), but if I truly won't have a use for it I need to stomp on that part of myself and just make some money off it.Thanks everyone!

content: Useful for checking that an IR remote controller is generating its IR signal. (a mobile phone camera can also do that though)Useable as a night vision scope provided you also use a suitable IR illuminator.Imaging some IR lasers to determine beam shape and collimation on a target.Detection of covert IR illumination that is part of a surveillance installation. (Active IR illumination is not exactly covert though)Sadly these units are more of a collectors piece unless the above uses appeal to you. They have no image intensifier functionality so expect unity gain at best. I have the tubes and high voltage modules out of Find-R-Scopes but have never found a use for them.Fraser

content: Here's some reference photos of the plug on mine in case it will help anyone in finding them (attached, sorry about them being crappy phone photos). Then figured accurate measurements would also help (also attached). I wasn't happy with my attempts to convey the dimensions so I made a full accurately dimensioned 3D model (and then labeled orthogonal images of that)...Some measurements rounded to closest 0.05mm (due to 0.01mm tool accuracy and difficulty in measuring some areas). I checked the camera connector dimensions and there is plenty of clearance with my model.Also, here's the specs for the wall wart: (these seem to be easy to find and cheap, albeit with the wrong connector)Type: Switching Power SupplyMake: CMPModel: S040EM1200300P/N: 10231014Input: 100-240V AC 50/60Hz 1.2AOutput: 12.0V DC 3000mA3D Model:(untested)The plug is accurate, I did take some liberty with the rear, adding 2mm to make up an anchor to mate with the molding. I also combined the metal shell and plastic center into a single part. Other than that, the only other thing I changed was shortening the upper 3x holes (from 7.30mm to 1.50mm) and adding a 1.15mm long opening 0.35mm from the end that the tips of the pins go into (since I was unable to measure the real internal opening offset & size). The molding itself is close to accurate but I was less concerned with an exact duplicate. I made the gaps between parts (molding/plug) 0.1mm, so it will be a tight fit.The only thing I left outare the holes for the wire to enter the molding and the holes in the plug for the pins since I didn't know what pins to use (I'll leave that for someone else to determine). If someone finds pins they like, I can add holes and re-post.Due to the small dimensions, it should be printed on a high resolution SLA type printer.It's created with SketchUp Make 2017 and converted to stl, licensed GNU. I don't currently have a 3D printer, so if anyone tries it, let me know if anything needs to be adjusted, or you can adjust it yourself and post it here or to Thingiverse, either way.(If it works out, it'd be awesome if someone would be willing to print and pin one I can buy :)

The closest thing to that now is the T3, at 384x288.I'm aware of export restrictions and limits on frame rates.A decade ago, the thought of an average joe being able to get a VGA sensor was unthinkable and financially prohibitive (even today it's quite expensive), but perhaps there's some hope in the future for us amateur usersThermal photography will get better if it's going to happen.

Last, FLIR is not an option for me.To anyone aware of a less expensive camera with similar characteristics, feel free to contact me in private.Thanks in advance for any hint :-)

content: These cameras return a single image where the top 256x192 pixels represent a dynamically balanced grey scale image, and the bottom 256x192 represent the raw temperature data. The image is a 32 Bit BGRA (Blue, Green, Red, Alpha). The Alpha channel (A) is reserved for creating transparent masks in formats that support transparency, like PNG and TIFF. The camera does not put anything in the A channel, but the other three channels contain data, which is strange because you only need two bytes to contain the entire temperature range of the camera sensor 0 to 655.35 Kelvin. This is usually represented in 0.01mK increment, so it fits nicely in the U16 range 0 - 65535.
