Description

technical field [0001] The invention relates to the technical field of optical measuring equipment, in particular to a 360-degree centripetal scanning solar simulator. Background technique [0002] A solar simulator is a simulated light source that provides a spectrum matching the solar radiation. It is often used in the fields of aircraft attitude calibration, remote sensing technology, and space environment material reflection characteristics measurement. According to different application fields, the requirements for key parameters of solar simulators such as spectral distribution, light source stability, light source irradiation uniformity, and irradiation intensity are different. With the continuous development of aerospace technology, many optoelectronic devices and functional materials in aerospace vehicles need to be tested for ground characteristics, and when testing material characteristics, it is necessary to perform combined tests on different irradiation angles...
