Abstract

The invention discloses a non-coated optical laser reflector array assembly, which comprises a plurality of polarization state space laser reflectors, far-field light spot forms of laser emitted by the polarization state space laser reflectors are periodically overlapped at intervals of a first angle, and the first angle is determined according to the angles of reflecting surfaces of the polarization state space laser reflectors; and according to a target structure, the installation azimuth angles of the polarization state space laser reflectors and the angle interval determined by the first angle and the number of the polarization state space laser reflectors, the polarization state space laser reflectors are arranged. According to the embodiment of the invention, the uniformity of the separated diffracted beam ring is improved through a reasonable spatial arrangement mode, and the problems of rare and unstable data volume of a ranging blind area caused by insufficient number of reflectors and overlarge separation angle are further compensated and solved.

Description

technical field [0001] The invention relates to the technical field of laser ranging, in particular to a non-coated optical laser reflector array assembly and a laser ranging system. Background technique [0002] In the field of aerospace, the laser reflector is a necessary component for tracking and measuring the distance of satellites and aerospace vehicles. It is a passive optical device and is mounted on the surface of the aircraft. In order to realize the long-distance precision measurement between the ranging point and the aircraft. In addition, it is also widely used in the precision measurement of objects such as long-distance targets. [0003] As a traditional laser reflector, its working technical status (divergence angle, maximum inclination angle, effective emission area, emissivity, far-field diffraction spot, velocity aberration compensation, etc.) is determined by the characteristics of the reflector (shape, size, angular error) Determining, for example, the...
