摘要： The basic idea is as follows: operational simulations of subtractive focal planes, based on the French patent No. 2 756 666, have shown that the optimal subtraction rate should not be total in order to preserve the dynamic range of the system. In this case, the low-frequency fluctuations of the temperature of the focal plane of the bias voltages will be amplified and will give rise to a fluctuation of the mean gray level of the signal at output of the multiplexer. This variation can be corrected simply by: the making of several columns of subtractive pixels without diffraction grating, for which the integrated signal is directly the residual level of the thermal current; the integration of a comparator circuit at input of the electronic card to subtract the signal generated in the reference pixels from the signals integrated into the active pixels.
