METHOD OF OBTAINING FOUR-DIMENSIONAL BRIGHTNESS-SPECTRAL PROFILES OF REMOTE OBJECTS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC G01S17/06 

FIELD: optics.

SUBSTANCE: invention relates to optical methods of obtaining information. Method and device for obtaining four-dimensional brightness-spectral profiles of remote objects are realized by obtaining in the main optical system in the full solid viewing angle of characteristic heliocentric two-dimensional sets of spectral beams from the observed objects with subsequent conversion by the microlens array into a set of four-dimensional sub-aperture spectral images of the aperture of the main optical system on the surface of the photodetector array. Algorithmic signal processing by the type of a plenoptic camera from submicrolens groups of photodiodes provides the formation of a set of spectral layers of the observed space, which enables to detect objects in both narrow and any preset spectral range. Obtaining coordinate, non-coordinate information and detection of objects is carried out by algorithmic processing of an array of spectral images.

EFFECT: high probability of detecting and identifying objects, high accuracy of determining coordinates and geometric features of objects.
