Abstract

The invention relates to an optical axis parallelism calibrating system and a calibrating method. The optical axis parallelism calibrating system includes an auto-collimation theodilite, a data processing computer, and a plane mirror used for auto-collimation for the auto-collimation theodilite, wherein a to-be-tested optical system is arranged on an emitting light path of the auto-collimation theodilite, and is electrically connected with the date processing computer. The optical axis parallelism calibrating system and the calibrating method provided by the invention have the advantages of high testing precision, excellent real-time performance and wide application range.

Description

technical field [0001] The invention belongs to the field of optics and relates to a calibration method, in particular to an optical axis parallelism calibration system and calibration method. Background technique [0002] With the development of science and technology, military photoelectric weapon equipment has more functions and higher performance indicators, and generally includes multiple photoelectric sensors such as TV, infrared, and laser, which can complete the search, capture, tracking, aiming, and imaging of targets. And laser irradiation and other functions, the spectrum of these optical devices covers almost all bands from visible light to infrared, not only the physical characteristic parameters of the target but also the spectral characteristic information of the target can be obtained. For this kind of equipment that integrates multiple optical instruments, the problem of parallelism of optical axes between many optical systems will inevitably arise. The par...
