Three-dimensional universal full-angle optical measurement platform for space optical remote sensor

Abstract

The invention discloses a three-dimensional universal full-angle optical measuring platform for a space optical remote sensor, comprising a stable platform, a lifting platform, a translation platform,an azimuth circular guide rail, a pitching arm, a rolling guide rail, a light source moving platform, and a detector moving platform. The lifting platform and the azimuth circular guide rails surrounding the lifting platform are mounted on the stable platform. The lifting platform is provided with the translation platform which comprises a stacked X-direction and Y-direction translation platform.A pair of pitching arms are mounted symmetrically and slidably on the azimuth circular guide rail. The two pitching arms are erected with the rolling guide rail which has a semicircular structure. Alight source moving platform and a detector moving platform are slidably mounted on the rolling guide rail. In the process of measurement, assembly and calibration, a tested instrument is placed on the translation platform, and independent changes in seven variables such as the three-dimensional coordinates of the position of the tested instrument, the incident azimuth angle and the zenith angle of the light source, and the receiving azimuth and zenith angle of the detector are achieved by an automatic control system and an actuator. The function of the platform is easy to expand and has highpracticability.

Description

technical field [0001] The invention relates to the field of optical measurement devices, in particular to a three-dimensional universal all-angle optical measurement platform for a space optical remote sensor. Background technique [0002] A spaceborne space optical remote sensor analyzes the distribution and changes of atmospheric components by detecting the multi-channel broadband optical radiation reflected and scattered by the earth's atmosphere or surface. The assembly and debugging of the optical components of the instrument is the key point of the system assembly; the test of the optical performance of the instrument is the key to measure whether the system can work normally; the ground calibration of the instrument is the premise and basis for the quantification of remote sensing data. In order to provide optical measurement means for instrument installation, testing and calibration, improve the quality of instrument installation and adjustment, provide quantitative...
