ADAPTIVE SYSTEM OF APERTURE PROBING FOR COMPENSATION OF WAVE FRONT DISTORTIONS IN LASER SYSTEMS Russian patent published in 2024 - IPC G02B26/08 

FIELD: optical instrument making.

SUBSTANCE: in the known adaptive system, the laser unit additionally includes two controlled flat mirrors CM, two centre of gravity measurement units CMB, a separation unit SU, an additional optical system (AOS), two light filters LF, and a calculation unit CU, which form two compensation circuits of angular deviations of optical axes of laser beams. BO is made with additional second output. First compensation circuit of deviation of axis of probing radiation includes output of OS-2, CM-3, AOS, SU, LF and input of first CMB, output of which is connected to control input of CM. Second circuit for compensation of deviation of the axis of the main radiation includes an optical output OS-1, second units of CM, AOS, SU, a second LF and an input of CMB, the output of which through the first input of the CU unit is connected to the control input of the CM, and the second input of the CU is connected to the output of the first CMB.

EFFECT: high accuracy of the adaptive system.
