The subject matter of the invention is a method of high-resolution acousto-optic programmable filtering in the infrared region of an incident optical wave. Each page buffer is connected to corresponding bit lines through a first column decoder circuit and connected to one corresponding output buffer through a second column decoder circuit. Each direction of recording lies essentially opposite a direction of illumination such that at least one contour of the object is visible with an illuminated side and a shaded side thereof from each of the three directions of recording while substantially the entire object is recorded from the at least three directions of recording by the at least one imaging apparatus.
