Compensation of IR-sensor Fixed Pattern Noise during Point Object Magnitude Recovering
Abstract:
The paper is devoted to describing a principally new method of recovering pulse magnitude which is the reaction of infrared (IR) scanning linear sensor on strobe light spots from point objects. Instead of traditional matching filtering where it is impossible to take into consideration deviations of the pulse magnitude and form depending strongly on a random spot position relatively photosensitive elements, fixed pattern noise (FPN) of sensitivity and FPN of dark current, the suggested method is almost invariant to FPN. The method uses the digital pulse stabilizer based on so-called probabilistic relay. The experimental results have shown that the suggested methods allows not only recovering both magnitude and form of the pulse sequence with good accuracy but leads to improving the quality of the formed image because the inverse coefficients of the stabilizer multiplier can be used for “on fly” IR-sensor calibration.
