PULSE LASER LOCATION SYSTEM Russian patent published in 2018 - IPC G01S17/06 

FIELD: optics.

SUBSTANCE: invention relates to the field of optical location and relates to a pulsed laser location system. System comprises a pulsed laser, an output optical system of a transmitting channel, a photodetector device for recording the angular momentum of a laser pulse, a one-axis scanning device, an optical objective of a photodetector device, a computing device, an array of photodetector devices, as well as a fiber-optic bundle, which, on the one hand, faces the ends of the fibers to the corresponding photodetectors of the array of photoreceptors, and on the other hand, the ends of the fibers of the tow are facing the output of the optical objective of the photodetector device and are located in its focal plane, the output of the photodetector laser pulse moment detection device is connected to a clock input of the computing device, the laser synchronization input is connected to the synchronization output of the computing device, and the outputs of the photodetectors of the array of photodetector devices are connected to the measuring inputs of the range of the computing device. System is characterized in that the output optical system of the transmission channel includes optics forming an astigmatic laser beam with a ratio of angular divergences along the orthogonal coordinates θ_x=Mϕ, θ_y=Kϕ, where ϕ – angular resolution of the system. Array of photoreceivers includes M*K photodetectors (M≤K), and the fiber-optic bundle contains M*K fibers, which on one side are facing the corresponding photodetectors of the array of photoreceptors, and on the other hand, the ends of the fiber bundles are mounted in an M-row array of MK fibers of K fibers in a row, with a large divergence θ_y corresponds to a coordinate parallel to the axis of rotation of the one-coordinate scanning device and the orientation of the K-fibers in the focal plane of the optical objective of the photodetector device, less divergence θ_x corresponds to a coordinate perpendicular to the rotation axis of the scanning device M of the system resolution elements, and the diameter of the optical fiber in the dashboard d and the focal length of the objective lens F are selected from the condition d/F=θ_x/M.

EFFECT: improving the quality of the location frame, reducing the time of the survey, reducing the overall mass characteristics of the location system, an increase in the reliability and informativity of the laser locator due to an increase in the uniformity of the power flux density along the section of the probing laser beam.
