Poor Man's Thermographic Camera 2

UPDATE: http://floba.info/content/passion/passion/Thermocam/ALowCostThermographicCame...

75 % of households' energy consumption is used for heating. The main reason is bad insulation, which can be measured with thermographic cameras. But these are still very expansive, e.g. 10000 € for a camera with a real resolution of 160 x 120 px and a frame rate of 20 fps. After http://www.youtube.com/watch?v=N1fV20gTEr0 we enhanced the idea of using a pyrometer's sensor, measure single points and stitch them together to an image. To keep oscillations at a minimum, we rotate infrared mirrors (pieces of a cake lifter -- it just needs to be polished metal!) in front of the sensor instead of panning and tilting the sensor itself. This video shows the results and further improvement and modification ideas. Our prototype costs around 100 €, has a real resolution of 80 x 80 px at a frame rate of 1 fpmin.

It should be possible to enhance the resolution e.g. with 3:53 or better optics (more than the used 1:30). Using it in multipurpose goggles and generate infrared images with this technique shouldn't be easy, because you must not move for 60 secs. But I could imagine to use 2nd approach of /watch?v=N1fV20gTEr0 in such googles...

Where can I find a sensor like this? I tried to look for it, but all I could find was detector sensors that only gave me a 0 or 1 at the output.

I'm wondering if it might be possible to sense multiple points at once without significant increases in size--similar to thermal imaging devices but maybe not as large. Seems like the best would be some kind of array sensor picking up 3x3 pixels or something like that, similar to the thermal imaging but maybe not as large or as fast. Any thoughts?

this is a massive work! amazing.

i dig what obalitas says, go to kickstarter and start a project! i'd like to support you!

[obalitas]

You should go to kickstarter com and do a project there!

is there a way tho enhance the resolution of this and put it into a smaller package suited for the use in multypurpose goggles?
