It is so compact and lightweight, that I mainly using it on my drone with a self developed driver on a raspberry pi to stream evaluated image data with openhd to my ground station.

The price disparity between those cores and the 640x512 cores always surprises me, especially when the tau 2 cores have been out for nearly a decade. I spoke with Fairchild a while back asking them to integrate the TWV1912 but I suppose there isn't enough market for UAS...

Can you move the lens further away from the sensor to reduce focus distance?

Excellent suggestion

[@tissuepaper9962]

The lens attached to the sensor is screwed on and then held in focus by a little drop of glue. You can just break the glue and then you'll be able to adjust the focus to your heart's content.

Nice camera and work getting it going! Another alternative to capturing the digital video would be one of the Pleora iPort PT1000 models (there's an RS422 variant with the right connector, even), which can be used as a gigabit ethernet camera - though this could be a little too low bandwidth for your highest framerates. I've got a somewhat similar camera with an equally hard to decypher command scheme that I got capturing through one, but I haven't yet been able to work out a usable set of commands to do the FFC, adjust gain settings, or map the greyscale output to color or otherwise. As your camera likely has similar thermal sensitivity, if you move your head outside of the autoranging ROI and exhale into the frame, you can probably see the heat from your breath, which is pretty neat looking. Heating your CNC chamber slightly or cooling the air in the airline to cool the workpiece even a few degrees will probably give you a visualization of the airflow around the workpiece with a camera this sensitive, could be worth a look!

marco, if you look at your graph at 13:56, you can see a blue peak at 3.3 micro meter (near h2o) : that's ch4 (methane). your camera seems to be able to detect it, try with a lighter, normally the natural gas (mainly ch4) should be visualised as black.
