The invention discloses a digital field of view detection system and method for optical equipment with a priori judgment. board; where the collimator and the reticle are jointly used as the target generator; the digital front mirror assembly is used to collect the image of the target generator after being imaged by the optical system to be tested; the host computer is used to control the digital front mirror assembly The image is collected and used to display the image at the same time, and the collected image is processed to realize the detection of the field of view of the optical system to be tested. Methods The a priori judgment of product qualification and field of view detection are realized based on the above system. By designing a special reticle, the invention can not only realize the detection of the digital field of view of the optical system, but also has a priori judgment of product qualification, and has the advantages of simple and efficient measurement process, high convenience, accurate measurement results and wide adaptability Etc.
Description
technical field [0001] The invention belongs to the field of low-light field of view detection, in particular to a digital field of view detection system and method for optical equipment with prior judgment. Background technique [0002] With the increasing perfection of optical system applications, the demand for testing and evaluation of the field of view of optical systems is also increasing, especially for low-light optical systems. Since the optical system has high requirements on the working distance and precision, the large field of view optical system can provide more information and play a great role in the detection of the system, so as to improve the use efficiency, which is one of the development directions of the current optical system 1. With the development of low-light technology, the size of low-light instruments is getting larger and larger, so there is an urgent need for a low-light optical system with a large field of view to match it. [0003] Due to th...
