Description

technical field [0001] The invention belongs to the field of optical measurement, in particular to a test device for measuring the object square angle of a small magnification white light and low light aiming system. Background technique [0002] In the prior art, object square angle measurement is widely used in surveying and mapping instrument detection, optical measurement and other fields. The object angle of the sight generally refers to the object space angle parameters of the optical system including the variation of the collimation axis, the resolution, the accuracy of the meter, the range of the meter, and the field of view. These parameters directly affect the performance of the sight. Therefore, these parameters The detection of the sight is very important, and it is the basic guarantee for it to work normally. [0003] At present, in order to realize the detection of these parameters, multiple instruments and equipment are usually required to complete, such as t...

AI Technical Summary

Problems solved by technology

Even though a detection instrument that can measure multiple parameters at the same time has been developed, due to the difference in the accuracy requirements of the measured parameters and the requirements for the target pattern, this type of instrument needs to replace the reticle according to the measured parameters, which is difficult to guarantee High-precision detection

In addition, among the object angle parameters, some have high requirements for the resolution of the optical system of the detection instrument, such as the change of collimation axis, resolution, mounting accuracy, etc., and some require the optical system of the detection instrument to have a large field of view, while for the optical system Speaking of large field of view and high resolution are contradictory, that is to say, the high-resolution optical system has a small field of view, and the resolution of a large field of view is not high.

Therefore, it is very difficult to realize the detection of all parameters of the object square angle on the same set of instruments and equipment
