Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a vacuum optical detection system. Background technique [0002] Considering that the space optical remote sensor works in a space low-pressure (approximately vacuum) environment, in order to test the performance of its optical system closer to reality, it is best to carry out the detection of the optical system under low-pressure conditions. [0003] Under the existing technical conditions, the detection of space optical remote sensors is generally carried out under laboratory conditions. With the increase of the aperture and focal length of optical remote sensors, the influence of atmospheric disturbance in the laboratory environment on optical detection is increasing. bigger. At present, the influence of atmospheric disturbance on optical system detection can only be reduced by ensuring that the airflow in the laboratory is stable, but it is impossible to fundamenta...
