Talk:Thermographic camera

message: Additional Proposal to Change Article:
FLIR - Forward Looking Infrared Cameras are military infrared systems designed to look down and forward (generally from aircraft). As Such, I am removing the first reference to Flir.
http://www.militaryinfrared.com/
FLIR is also a brand name of camera, as is Fluke. These are two of the most common ones. I believe the author who wrote that FLIR cameras are essentially the same as infrared cameras has this counfusion as a result of this.
I am a Nachi-Certified Infrared Inspector and use the Fluke TI-32 for most applications. Feel free to hit me up on my talk page to ask for images. I am more than happy to either upload ones I already have, or take ones specifically for this article.

replies: text: I agree completely, as a result I decided to be bold and rename the article to thermographic camera. The existing article seems to confuse near and far infrared seeing but focus mostly on far, I'll make a quick pass to remove more of the near IR stuff and it can grow from there.

message: I made some changes to this section for factual errors and clarity. I changed "every episode of Ghost Hunters and other paranormal programs" to "Some episodes of Ghost Hunters and other paranormal programs" because the thermal camera is not used in every episode of Ghost Hunters (much less every other paranormal program ever aired, as implied). While the findings in nearly all of those episaodes cannot be proven to be anything but false positives, they also haven't been proven not to be. In the spirit of the fact that (from a strictly scientific perspective) they are likely to be false positives, I kept that language in. I also linked to the wikipedia article on false positives. --AnalogWeapon (talk) 16:35, 10 May 2011 (UTC)

message: Can a normal visible-light digital camera with a charge coupled device be modified to function as a low-cost amateur temperature sensing heat-field camera? 
This question is mainly due to the fact that big-name companies like FLIR charge ridiculous sums of money for low resolution professional thermographic camera systems. Woohoo, $20,000 for a "FLIR T620" 640x480 thermographic camera:

I have seen several types of standard CCD camera modifications explored separately on the web. Can these be combined to achieve amateur IR thermographic imaging at low cost?
1. Give basic IR detection capability to a standard CCD camera by removing a manufactuer-installed IR filter over the CCD, and installing a visible-light filter over the lens:
* http://www.astrosurf.com/buil/d70/ircut.htm
2. A homemade CCD chiller using dry ice, for DSLR astronomy photographs with less noise, would also improve CCD sensitivity to ambient IR. Normal CCD sensitivity keeps improving when chilled down to about -170 C before performance declines again, and dry ice sublimates at -70 C so this allows for easy amateur low-temperature regulation:

4. Canon cameras can be hacked and reprogrammed to do things never intended by the manufacturer, with the Canon hack development kit (CHDK). Is thermographic imaging possible just by using new programming to read the CCD differently?
* http://chdk.wikia.com
Also, refrigeration systems mainly work by creating a temperature depression relative to ambient, and peltier coolers can easily manage about 30 C temperature difference, plus it is solid state device with no specific operating range like pressure-based refrigerants, so a peltier removing heat from a CCD, and transferring the heat to sublimating dry ice should allow amateur cooling to -100 C with not much cost.
