The device comprises a multi-directional adjustable platform,an optical sight, a high-precision level meter, an aiming and positioning line and accessories, and parallelism calibration of the optical axes of the spatial large-span calibration system can be achieved. The idea of unified reference is adopted in calibration, and the calibrated axis calibration system can provide the unified optical axis reference for the spatial large-span axes in the to-be-calibrated system. The system has the main advantages that common collimators are used, calibration of the collimators is completed indoors by using conventional optical elements and an adjusting platform and is not affected by external weather, and operation is simple.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a large-span multi-optical axis calibration system and its calibration device and method. Background technique [0002] In a general photoelectric system, the distance between the optical axes is small, and it is often completed by adjusting the optical axis with a large-diameter collimator. For large-scale systems, the space between the shafts is large, the position is high and low, and the left and right spans are greater than 2 meters or even larger, which cannot be completed by the above method. At present, the "small aperture optical tube method", "large aperture optical tube method", "star aiming method", and "target plate method" are often used in optical axis adjustment, among which the first two methods use collimated optical tubes to establish Fix the reference, after the system under test is directly aligned, the laser channel of the system under test emits a laser b...

Problems solved by technology

[0003] Aiming at the problem that it is difficult to complete the alignment of optical axes with a large space span indoors, this patent proposes a multi-optical axis alignment system with a large space span and its adjustment device and method, which can complete the parallelism of the optical axes of the alignment system indoors. Calibration and optical axis calibration of the system to be debugged

Its innovative point is that the parallelism calibration between multiple and long-span optical axes can be completed indoors. Using this method and device can solve the problem that the current long-span axis calibration can only rely on meteorological conditions, and the methods all use common Optical components and debugging platform without special materials and components
