Abstract

The invention relates to a parallelism detector for an optical axis of a multi-optical system. A first half-reflecting semi-permeable mirror of the detector is fixed on a guide rail, and a calibration reflection mirror is movably connected with the guide rail through a two-dimensional adjusting mechanism; a refluxing reflection mirror is movably connected with a guide rail sliding block through the two-dimensional adjusting mechanism, and the guide rail sliding block can move along the guide rail; a crosshair division plate is positioned on a focal surface of a collimating system, and a light source irradiates one side of the crosshair division plate; one path of collimated light beams emitted from the collimating system permeates the first half-reflecting semi-permeable mirror and is then incident upon the calibration reflecting mirror, and the other path of the collimated light beams is incident upon a cone prism after reflected through the first half-reflecting semi-permeable mirror and the refluxing reflection mirror. The invention can be flexibly applied to the parallelism detection of optical axes of various multi-optical systems and has simple processing and manufacturing, low cost, convenient installation and debugging and convenient detection and calibration.

Description

technical field [0001] The invention belongs to the technical field of optical instrument inspection, and relates to a multi-optical system optical axis parallelism detector. Background technique [0002] With the development of science and technology, the application of multi-sensor optoelectronic equipment is becoming more and more extensive. Not only the various optoelectronic theodolites used on the ground, but also the new aviation airborne optoelectronic equipment have infrared, visible sensors and laser ranging systems at the same time. The three optical systems are used to test the same target. In order to ensure the consistency of the measurement results, the optical axes of the three optical systems must be parallel. Due to the large difference in the distance between the optical axes of the three optical systems, a large-diameter collimator cannot be used for testing, and the laser ranging system is actively emitting light, which is different from infrared and vis...
