The article is concerned with the utilization of the Mach-Zehnder twin-wave interferometer in the system of correlational processing of spatial optical information using the photoelectric detection. In the first channel of the interferometer an information Transparency, containing an image to be analysed, is placed. In the second channel the another one is placed. The transmittance of the latter characterizes the structure of the filter, conforming directly to the definite image. The use of the scheme of the twin-wave interferometer permits to decrease coherence light requirements, allowes the information processing in continuous mode, increases the flexibility of the scheme, because various transformations of light fields can be performed in each channel.
