METHOD OF DELIVERING TO POINT TARGET OF LASER RANGE FINDER RADIATION Russian patent published in 2020 - IPC G01C3/08 

FIELD: quantum electronics; measuring equipment.

SUBSTANCE: method of delivering a laser range finder to a point target of radiation is based on a unique connection of the refraction angles of optical beams with the ratio of temperature of water on the surface of the sea and air in the driving layer of the atmosphere. In order to compensate for the error in the target designation data from the television channel due to different refraction of the television and laser channel beams in the atmosphere, adaptive correction of the target designation data for the laser range finder, for which the spectral refractive index of air is calculated at the central operating wavelength of the television channel. Simultaneously, the spectral refractive index of air is calculated at the central working wavelength of the thermal imaging channel. Also, calculating spectral refractive index of air on central operating wavelength of laser channel, then, current values of air temperatures in the atmospheric and water driving layer are measured on the sea surface, the difference between the measured air temperatures in the atmospheric and water drive layer on the sea surface is calculated. Further, angular coordinate of target in vertical plane is measured using television channel and angular coordinate of target in vertical plane using thermal imaging channel, then their difference is calculated. Further, the laser beam aiming angle in the vertical plane is determined. Further, the laser beam is shifted by the calculated angle in the vertical plane. Finally, the laser beam is sent to the target.

EFFECT: compensating for the effect of optical refraction when the laser channel of the active-passive optoelectronic system is aimed at the point target.
