The invention relates to an overall design method of a large-caliber high-precision solar simulator, wherein the overall design method comprises the following steps: I, designing and determining a solar simulator main light path according to the site requirement of a solar simulator; II, determining the position of a light source according to the designed main light path parameters; III, designingintegrator parameters, and designing a small optical axis of an integrator into a divergent type; IV, designing a mode of splicing a plurality of reflection units into a collimating mirror so as to form a collimating mirror similar to a paraboloid; and V, arranging the light source on one side of the integrator, and arranging the collimating mirror on the other side of the integrator. The overalldesign method of the large-caliber high-precision solar simulator has the advantage of realizing large-aperture high-precision long-distance uniform solar irradiation simulation in a limited space.
Description
technical field [0001] The invention relates to the technical field of solar simulators, in particular to an overall design method for a large-diameter and high-precision solar simulator. Background technique [0002] With the expansion of human activities into space, the study of space objects is becoming more and more important. Optical means have unique advantages in space target detection. The acquisition methods of radiation and scattering characteristics of space targets mainly include ground-based data verification methods and space-based data verification methods. Space-based optoelectronic equipment to achieve space-based data acquisition, such as Hubble, etc., has the disadvantages of high cost and high technical difficulty. The ground-based observation mainly adopts the establishment of a large-aperture observation station on the ground, and calibrates the detector by measuring the magnitude of known stars, and then realizes the magnitude measurement of the spac...
