Abstract
An apparatus to measure the time constant of microbolometer-type uncooled thermal imaging camera pixels on a per-pixel basis has been developed. The apparatus utilizes a longwave infrared laser and acousto-optic modulator as a periodic light source to excite the pixels of the camera's focal plane array. The image frames captured by the camera during excitation are then processed and the data fit using the algorithms developed to find the time constant for each pixel in the array.
