METHOD FOR DYNAMIC CONTROL OF ALIGNMENT OF DIRECTION-FINDING AND LASER CHANNELS Russian patent published in 2023 - IPC G01C3/08 

FIELD: laser location.

SUBSTANCE: laser location and precise guidance of laser radiation. Method consists in introducing an auxiliary bidirectional beam of optical radiation, in the reference direction the beam goes to the auxiliary matrix photodetector, generates a signal about the position of the reference direction of the beam, is compared with the signal received at the auxiliary photodetector by laser radiation from the laser through a two-coordinate mechanism for correcting the direction of laser radiation and a node optical conjugation of the reference beam and division of laser radiation, the mismatch signal of the reference direction of the beam and laser radiation controls the two-coordinate mechanism for correcting the direction of radiation to achieve collinearity. In the information direction, the radiation beam goes to the optical assembly, the laser radiation output and the bearing signal input, enters the direction-finding photodetectors through the division node, generates signals about the reference direction, the mismatch signal between the target bearing and the reference direction in each photodetector controls the optical assembly so that the bearing signal coincides with the reference direction signal, which is the aiming point, when one of the direction-finding photodetectors is assigned as the leader.

EFFECT: high pointing accuracy.
