Abstract

The invention discloses a method for detecting the environmental test stability of a camera unit. A detecting device including an optical platform is installed; a shearing frame I and a shearing frameII are installed on the optical platform at an interval; a PSD self-collimator is arranged on the shearing frame I and a camera unit is arranged on the shearing frame II; the heights of the shearingframe I and the shearing frame II are adjusted and the optical axis of the PSD self-collimator is controlled to be at the same height as the optical axis of the camera unit; the optical axis positionsof the self-collimator and the camera unit are adjusted to ensure that the deviation angle of the self-collimator is zero; and then the camera unit collects an image of the self-collimator and determines the location of the image of a cross reticle in the image, the locations of the images of the cross reticle in the images before and after testing are compared, and the stability of the camera unit after prescribed environmental test is determined. The detection method has advantages of simple structure, convenient adjustment; and rapid building and measurement at the test site are realized conveniently; and the environmental impact factor is small.

Description

technical field [0001] The invention belongs to the technical field of photoelectric testing, and relates to a detection device for the environmental test stability of an imaging device, and also relates to a detection method for the environmental test stability of the imaging device. Background technique [0002] With the continuous expansion of the application field of CCD imaging devices, more stringent requirements have been put forward for the use environment they can withstand. It is hoped that they can withstand harsh conditions such as shock, vibration, high and low temperature, and improve stability and reliability. In order to verify whether the optomechanical structure and CCD focal plane structure of the CCD imaging device have changed after various environmental tests, so as to provide a reference for further performance testing, it is necessary to adopt a certain test method to compare the optomechanical structure with the CCD focal plane structure. Changes in ...
