METHOD FOR COMPENSATION OF PHASE DISTORTIONS OF WAVE FRONT BASED ON LIGHT FIELD Russian patent published in 2023 - IPC G01N21/41 G02B27/00 G01M11/02 

FIELD: atmospheric communication lines.

SUBSTANCE: invention can be used in atmospheric communication lines of information coherent optical systems that are critical to wave phase fluctuations, as well as in adaptive optics systems of astronomical telescopes. The method includes the formation of an array of sub-aperture images in the plane of the photodetector. Correction of phase distortions of the wave front is carried out on the basis of mathematical transformation and a posteriori data processing. Registration of the observed volumetric region of space is carried out by a light field recorder. The wave front shape of the signal wave is analysed and a profile of the structural function of the refractive index is formed over the entire observed volumetric region of space. To compensate for image distortions, a new data object is obtained in which the travel directions of individual homocentric beams of rays will coincide with the unit vectors describing the reference light field, and the modules of the vectors will coincide with the registered light field.

EFFECT: increase in the accuracy of compensation for wave front distortions.
