Therm-App threaded lens mount/extension for experimentation - useful item :) - Page 1

content: In case it is of interest or use to others, I am detailing a lens mount thread adapter that matches the Therm-App lenses.The Therm-App uses an unusual thread for its lens mount. It is almost a standard C mount but sadly, not close enough ! The Thermal Expert uses a 25mm diameter threaded mount with a thread pitch of 0.5mm. The standard C mount uses a thread pitch of 32 TPI (~0.80mm pitch) and is slightly larger diameter, being a 1" mount (25.4mm).I purchased a Therm-App 19mm lens for a reasonable price and wanted to create a lens mount for it to screw into. I could make one on a lathe but I prefer to buy well made commercial items where able. The finish is often better and the thread is likely better than what I can produce !The 25mm diameter x 0.5mm pitch mount is better known as a "Schneider 00" mount and it is not that common when compared to other threaded mounts. I found a neat little adapter that converts a Schneider 00 lens for use on a Pentax M42 screw mount. At a cost of less than $10 delivered it made sense to order one. The adapter is perfect as a lens mount for the 19mm lens as there is a nice wide flat ring of metal around the M25 thread, plus, of course, the M42 x 1mm Pentax mount male thread. This facilitates all manner of mounting methods and adaptions to suit the project.As stated, I wanted a nice M25 x 0.5mm threaded mount in order to make use of the Thermal Expert lens. The adapter is perfect for that application but it may also offer something to Therm-App camera owners ?It has been known for some time that the Therm-App can provide excellent close focus, but the lens is at the end of its threads and almost coming out of the threaded mount in very close focus situations. The temporary addition of the M25 x 0.5mm adapter to the front of the cameras mount would provide a further 5mm of thread to support the lens barrel. In thermal imaging, 5mm of lens travel can be an awful lot when it comes to focus distance ! I see little reason why more than one M25 adapter could not be stacked to create a 10mm or longer extension for the lens. Not bad value at $10 each I think.The adapters dimensions are as follows:Female thread : M25 x 0.5mm pitch (Schneider 00 mount)Male thread : M42 x 1.0mm pitch (Pentax M42 mount)Outer flange diameter : 44.9mmOuter flange thickness : 1.46mmAdapter total thickness : 4.96mmFemale thread penetration into adapter : full thicknessWidth of adapter ring face female thread ID to male thread OD : 8.63mmWidth of adapter ring face female thread ID to outer flange OD : 10.14mmAdapter Material : Black anodised AluminiumI hope this information is of interest and help to others. These M25 x 0.5mm adapters are not common so I am providing the sellers details here:https://www.ebay.co.uk/itm/M25x0-5-to-M42x1-Screw-Thread-Lens-Mount-Adapter-Inner-M25-x0-5mm-Outer-M42-x1mm/372162509612?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649Fraser

content: I foundan interesting paperrecently (PDF) that discusses the design of an uncooled thermal sensor with 12µm pitch that uses mechanical resonance rather than microbolometer techniques. The authors explore a system where the resonant frequency of a micro-mechanical device varies with temperature. Sensitivity with the early prototype devices is nowhere near as good as a microbolometer - they're talking about 180mK NETD, compared with ~25mK for a good microbolometer array - but it's early days and they may be onto something. The paper includes some nice electron micrographs.

At $175 this is not cheap, but I'm used to paying that for good reference texts. Especially if they have a recent bibliography.Other suggestions welcome. If it does *not* have lots of mathematics, it's *not* what I'm looking for. Ideally I'm looking for 2-3 high level, high quality references. No matter how good the author, everyone leaves something out. By the time I have 3 references almost everything is covered except work done post publication.I'm particularly looking for noise processes, commonly used noise suppression techniques, etc based on the assumption the reader is familiar with such things.

content: Oh, I remember a list of references... It must have been on the artistic thermal imaging thread in the beginning. There was the project to bring it from the scientific to the artistic and commercial domain and they invested a lot into researching human perception on energy and somehow thermal images to make that visible. There was only a single technical reference in there so you have to see if that is worth a read.Otherwise you can try to find some answers from FLIR and their engineering datasheets of their cameras. Some references are only available towards developers(free signup) while a lot can be found with a little Google-Fu if you know your catch words. For example the Lepton engineering manual for OEMs includes a few pages on AGC, gain modes and how they play with the histogram to put a lot into visible parts of they greyscale. For their higher end sensors you can find similar papers with further explanation and examples.

content: I think you may need first to learn/understand the technology, as thermal noise may be specific to the technology used, i.e. uncooled microbolometers. For instance on the E4 the noise can be seen as "column" noise, mostly pronounced vertically in column like shapes, before calibration kicks in. This may dictate specific approaches to noise reduction.

Less expensive SWIR to MWIR camera - Page 1

content: I found this wide band IR imager that covers a band from SWIR all the way up through MWIR. Usually IR imagers only cover one band at a time, like SWIR, MWIR, or LWIR. This camera though covers SWIR and MWIR from 1000nm to 5000nm. I say "less expensive", not "cheap", because this is definitely not cheap. At a price of $4995, It's still out of the price range of the average hobbyist, but it's cheaper than some other SWIR camera's that I've seen. However, this lower price comes at a huge cost. It sacrifices resolution to be less expensive. The imaging sensor is a 32x32 array (total pixel count is 1024 pixels). This is a VERY LOW resolution. It seems like it would actually be unusable for most situations.Here's the link to the product in question.https://alliedscientificpro.com/shop/product/matrix-1024-core-s-22532

content: It appears that the manufacturer of this camera is New Infrared Technologies, which has developed a way to make uncooled MWIR and SWIR cameras. Typically, only LWIR cameras were available in both cooled and uncooled varieties, while SWIR and MWIR were all cooled sensors. MWIR used mechanical coolers, while SWIR usually used thermoelectric coolers. This NIT company though appears to have created SWIR and MWIR cameras that don't need any cooling, according to their websitehttps://www.niteurope.com/en/One interesting thing I notice that their website mentions is:"CMOS integrationImaging sensors monolithically integrated with ROIC-CMOS"I'm not exactly sure what "monolithically integrated" means, but it sounds like it might mean a one-step process to produce the SWIR or MWIR imaging sensor. Typically it's a 3 step process:Making the InGaAs chip for SWIR imaging (or InSb for MWIR imaging).Making the silicon readout chip.Then aligning the 2 chips are very precisely and welding them together in a way that doesn't damage them.In this case, it sounds like they may have developed a chip-making machine, that can handle both silicon and InGaAs (or InSb), which can create a single chip composed of both materials. If that's the case, it should MASSIVELY drive down costs for SWIR and MWIR cameras built in the future. Maybe they could even create a consumer level SWIR or MWIR camera in the future that's at a reasonable cost, in much the same way that FLIR created a consumer level LWIR camera when they created the FLIR One.

content: Excuse some of my terminology - it may get lost in translation!Those who are doing thermal mapping with the XT/Vue Pro etc: Have you had the issue of the thermal camera measuring different temperatures depending on the flight lines, making the thermal orthomosaic/reflectance map look striped?I thought this had something to do with the FFC, but it seems as colder temperatures = more pronounced lines. Would you think disabling automatic FFC would reduce this? Atmospheric temperatures 10°C and above show next to no stripes but they get very noticeable below freezing level °C. Wind and wind-cooling definitely seems to play a large factor as well.Also - do you have solutions for this? I've been thinking that adjusting the temperatures on every other flight line would normalize the map and minimize these stripes (my field of work does not necessarily need 100% exact temperatures but more of a guideline).Attached is a part of a map with said lines. Color ramp has a narrow temperature range. Warm and cold lines differ by about 2-3°C. This was taken at around -6°C, very little wind and with the sun very very low on the horizon (65°N)Edit: I'm using Zenmuse XT on DJI M210 and using PrecisionMapper (Photoscan) for processing.

Other cameras also have discounts, bringing a25Hz 384x288 ThermApp with 19mm lens and the usual accessories down to US$1300.No word on how long the sale is for, or when it started.Full details here.I was also interested to see they'velaunched a "high end" VGA core, a 17µm 640x480 with digital and analogue outputs, shuttered or shutterless operation. It's $4,500 so not cheap compared to the Therm-App cameras, particularly when you realise you have to add a case and optics.I know I always sound like an advertising agent for Opgal but I reiterate that I am not paid by them, nor do I receive freebies (other than a pair of spare USB cables that I asked for a couple of years ago).

content: Needed to use my i3systems Thermal Expert Q1+ today and got the image below. It worked fine last week.Tried it with a different phone and it works OK on there (subject to being difficult to get working in the first place, as usual). Seems to be more a phone problem than a camera issue, and coincidentally my phone had an Android update over the weekend. However, nothing else seems to be affected and I can't think of an obvious failure mode.Anyone recognise the issue?

I almost bought it but that is unfair to an owner of a Therm App who needs such a lens. I would modify it to use on another camera if I had bought it.https://www.ebay.com/itm/Therm-App-TA190000-0001-Additional-Lens-19-mm/192614732163?hash=item2cd8bb9183:g:rvcAAOSwatRbYfPuIf you need one, it looks like a decent dealFraser

When the icon,few minutes later, goes off, by pressing the "Return" or the "Playback" button the icon appears on the screen indicating charging process. I left it to fully charge to make sure is not a problem with a depleted battery.Try again to turn it on but no success.I connected it to the computer and I can see the internal storage of the FlirE4. When connected to FlirTools I got all options available but the "connect" does return a green screen from the camera (live view). I tried to remove the battery for 10 minutes but still no response.Any ideas on what is going wrong?Thank you in advance.

timestamp: October 03, 2018, 10:58:58 am
content: The main problem with the pinhole camera is that the area of the pinhole is very small, so only a small fraction of the incoming light is captured. To cope with the faint light coming from the pinhole, the photographer requires either very bright illumination of the subject, or very sensitive sensors, or very long exposure times.That is why we have lenses: a lens is "harvesting" the light from a much bigger area when compared to a pinhole, so a photo-detector will have a much easier job with capturing the image.

content: The lens is designed to work from 1200nm to 1700nm and that only covers infrared light while visible light is from about 600nm to 400nm. It seams to also work for visible light in that demo but it looses the low chromatic aboration feature. But i'm guessing they are aiming to make the technology also work for visible light in the future.

content: I came across a couple of varieties of hand-held device called 'Nocturna Sentinel'. I first saw them on eBay but there's a UK website, nocturna.co.uk - however the only details there are that the two basic grades of device are suitable for "up to 50m" (~£260) or "up to 100m" (£360-£460 depending on twiddly bits). They're described as a "compact hand-held infra red night vision system". It doesn'tsaythermal, but does say "can be applied effectively in covert operations" - which in my view rules out an active device like an IR LED and wide band CCD camera, because it's too easy to spot the glow (or bright, bright light if you're using anything from a Gen 0 image intensifier onwards).I can't find any indication of the resolution, lens details or, really,anythingtechnical.Does anyone have any ideas or info?(There's an ex-demo unit on offer for £130 - seeeBay auction: #123390156450

Not what I'd call "covert", unlike thermal and other passive solutions.Somewhere in my toybox I have some EVS / VNC extreme low light cameras. They are reputed to work in just overcast starlight (though I haven't seen a lens spec for that), however in my largely unlit edge-of-town location they five perfectly usable images from the reflection of street lights from clouds using an off-the-shelf CS-mount f/1.0 3-8mm zoom.

Integrated video camera HDMI out too.Rothenberger looks like a pipework technology tools company rather than an own-brand. Of course it has the standard Aldi 3 year warranty.As I say, I've no idea whether it's anywhere near in the price stakes, or whether it's related one of the newer Chinese ones but I though it might prompt a discussion.
