In this paper questions of deciphering data from farIR camera are discussed. The camera is of an original con struction, based on the optical-acoustic cells; it provides for the observation of the objects in the far infrared range (812 m). Readout of the data is conducted using a dif ferential polarization method. In the output plane on the optical system the interference rings appear. So some ap proaches of computer processing of the interference pattern were put forward. As a result several methods are proposed that can considerably widen the dynamical range of the de vice.
