FIELD: image forming devices.
SUBSTANCE: group of inventions relates to a multichannel spectral device for obtaining images with Fourier transform. Multichannel spectral device for obtaining images with Fourier transform comprises a photodetector having a plurality of photosensitive sections, located at the same level with the photosensitive surface, a collimation lens having an intermediate focal plane, a set of double-beam interferometers, each of which comprises a cavity limited by two sides, a set of microlenses arranged in a plane parallel to the photosensitive surface, wherein each microlens is connected to one interferometer, forming an optical pair having a focal plane, coinciding with photosensitive surface, and located opposite section of photosensitive surface.
EFFECT: technical result is high spectral resolution of monochromatic images.
