Problems solved by technology

[0003] Angle-resolved scattering instruments can obtain the spatial distribution of scattered light, so the research on angle-resolved spatial laser scattering measurement technology is of great significance. When using a conventional test platform for testing, only hemispherical space with a zenith angle of 0 to 90 degrees can be achieved. Scattered light measurement reduces test efficiency, and the pitch component is a cantilever structure with large deformation of parts, which affects the motion accuracy of the test platform

Abstract

The invention relates to a multi-angle laser light scattering measurement platform. The platform comprises a rolling assembly, a pitching assembly and an orientation assembly, wherein the orientationassembly is mounted on a foundation of a laboratory through an orientation foot margin assembly; a pitching axis assembly is formed by fixedly connecting a pitching U-shaped framework (13) with the outer rings of a pitching left bearing (34) and a pitching right bearing (14) through screws, and a rolling assembly is formed by respectively and fixedly connecting the left and right end surfaces of arolling framework (11) with a front slide block (2) and a rear slide block (4) through screws; and an irradiation light source (10) is mounted on the upper end surface of the rolling framework, can rotate in three degrees of freedom, namely + / -90 rolling degrees, + / -93 pitching degrees and 360 orientation degrees and can be accurately positioned at a specified angular position.

Description

(1) Technical field [0001] The invention relates to a laser scattering measurement platform, in particular to a multi-angle laser scattering measurement platform. It can be applied to the optical performance test of various media, especially the test of laser scattering performance of various media. (2) Background technology [0002] The interaction between the electromagnetic wave of the incident light and the particles in the propagation medium produces a scattering phenomenon. The scattering field distribution of an optical surface with a certain shape and dielectric properties is definite and contains information such as the geometric shape and electromagnetic properties of the optical surface. Laser scattering measurement has the advantages of wide measurement range, fast measurement, high measurement accuracy, non-contact and good repeatability. It has been widely used in the fields of semiconductor industry, surface inspection, biomedicine, aerospace, astronomical ex...
