Abstract :
In this paper the results of theoretical analysis of potential relief read-out in a pyroelectric vidicon for the principal variants of 3-phase scanning implementation are presented. Obtained analytical expressions allow determining the video signal and efficiency of potential relief read-out, the conditions of pedestal inhomogeneities and noise suppression, and so allow elaboration of an effective scanning mode.
