METHOD OF SEGMENTED MIRROR ADJUSTMENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC G02B7/185 G01B11/24 H01Q15/16 

FIELD: physics.

SUBSTANCE: invention can be used to control the shape of the surface of segmented reflectors of space and ground-based telescopes. Alignment of segmented mirror includes supply of radiation from radiator in the form of unit of rigidly fixed to each other emitters, number of which coincides with number of segments of mirror, and the radiation pattern of each radiator is rigidly fixed in space and provides for supply of radiation from each i element to the i segment of the mirror located at the distance of double focus from the mirror. Unit is configured to control each radiator element. Projected light spots from the mirror segment i are recorded with a matrix photodetector lying also at a distance of double focus from the mirror. Distribution of intensity and coordinates of centers of gravity of projected light spots and their deviation from sizes and coordinates of centers of gravity of light spots, which correspond to ideal mutual alignment of mirror segments, and signals are generated, which control positions of segments by displacement and inclination.

EFFECT: simplicity and convenience of complete adjustment of segmented mirror due to adjustment of each segment of mirror along longitudinal displacement and inclination.
