Abstract

A transmission test system and method based on the principle of self-collimation, which belong to the field of space optical remote sensor technology; the test method includes the following steps: S1, setting a target 5 at the focal plane position of the space camera system, the optical facet of the target 5 and The photosensitive surfaces of the focal plane detector 4 of the space camera system are located on the same plane; the plane reflector system 1 is set on the light entrance side of the space camera system; The surface component 3 and the lens 2 of the space camera system become a beam of parallel light with the information of the target 5; the parallel light described in S3 and S2 passes through the lens 2 and the focal plane component after being reflected by the plane mirror system 1 3. After arriving at the focal plane detector 4, a target image is formed; the transmission of the space camera system is calculated by using the target image.

Description

technical field [0001] The invention relates to a transmission test system and method based on the principle of self-collimation, in particular to a system and method applied to the transmission test of space optical remote sensors, belonging to the technical field of space optical remote sensors. Background technique [0002] The imaging quality of the optical system is an important index for evaluating space optical remote sensors. In the state of the whole machine, the optical transfer function (MTF, MTF for short) detection method is usually used for testing. This detection method is considered to be an accurate, objective and quantitative image quality evaluation index. [0003] With the improvement of the spatial resolution index of the space optical remote sensor (hereinafter referred to as the camera), the aperture of the camera is also getting larger and larger. When the camera aperture exceeds a certain level, the traditional horizontal adjustment of the optical ...
