News and discussions about image sensors
PTC and temperature. Starting to get less interesting.
Anon: do you have any idea of how revolutionary this sentence is?"So the variation in temperature can be realized by whatever means you have available, even with an hairdryer"This means you can evaluate any sensor and extract parameters without complicated measurement/optical setup. This would allow any person to cross-compare what has been provided by the manufacturer to the "real" sensor performance. I think that is a very interesting thing to do; something that all the "big guys" out there need to be wary of...
Please be aware that measurements in dark (with or without hairdryer) can only reveal the performance in dark : dark current, dark current non-uniformities, dark shot noise, noise floor in dark, FPN in dark on pixel level as well as on column level and row level, etc. Once you are interested in the performance in light (e.g. QE and PRNU) the hairdryer will not help you, unless the sensor can "see" the glowing heating elements ;-)
