Embodiment Construction

[0027] Invention idea of ​​the present invention is:

[0028] Under the premise that the interferometer and theodolite are used to ensure that the installation base surface of the multi-optical axis imager is perpendicular to the optical axis of the interferometer, according to the principle of wave measurement aberration of the interferometer, the optical axis of each channel is adjusted to the same optical axis as the interferometer. Therefore, while ensuring the imaging quality of each optical system, the adjustment of the parallelism of the optical axes of the multi-optical axis imager is realized, and each optical axis is perpendicular to the installation base surface.

[0029] In the adjustment of the parallelism of the optical axes of each channel, the principle of wave aberration measurement by the interferometer is used, that is, the spherical wave emitted by the standard spherical mirror of the interferometer becomes a plane wave after passing through the optical syst...

Abstract

The invention relates to a method for adjusting optical axis parallelism of a multi-optical-axis imager. The method includes the steps: assembling a standard plane mirror on an interferometer and adjusting a single-mode dual-plane reflector to be self-aligned; inversely placing an optical-mechanical structure of the multi-optical-axis imager between the interferometer and the single-mode dual-plane reflector; adjusting a mounting base surface of the multi-optical-axis imager to be perpendicular to the optical axis of the interferometer; assembling a standard spherical mirror on the interferometer and adjusting the position and the inclination angle of a first channel optical-mechanical system on the mounting base surface to enable the first channel optical-mechanical system and a standard spherical mirror system to be confocal; and adjusting the position and the inclination angle of a second channel optical-mechanical system on the mounting base surface to enable the second channel optical-mechanical system and the standard spherical mirror system to be confocal. In the method, no special devices are needed, multi-optical-axis parallelism and system wave aberration can be simultaneously adjusted, and adjusting precision and efficiency are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of multi-optical axis imager installation and adjustment, and in particular relates to a method for adjusting the parallelism of optical axes of a multi-optical axis imager. Background technique [0002] Optical axis parallelism is a key indicator to ensure that each channel of a multi-optical axis system observes the same target, and is crucial to the accuracy of target information comparison and inversion of each channel. Therefore, the parallelism of multiple optical axes has always been an important and difficult point in the adjustment and inspection of the multi-optical axis optical machine system. At present, the commonly used methods include projection target method, pentaprism method, beam splitting projection method, large aperture collimator method and so on. However, these methods require special equipment - poor versatility, rely on human judgment - are greatly affected by subjective factors, w...
