Abstract

The invention discloses an optical system definition test device, which includes an optical power controller, a light splitting structure, an energy detector, a controller, an acquisition system and a processor, wherein the optical power controller is used to input the light beam of the optical system output to the light splitting structure, and control the light intensity of the beam output to the light splitting structure; the light splitting structure is used to split the input beam into the first light beam and the second light beam; the energy detector is used to detect the light intensity of the first light beam; The controller is used to control the light intensity of the light beam output by the optical power controller according to the light intensity of the first light beam detected by the energy detector; the acquisition system is used to convert the second light beam into an electronic image; the processor is used to Clarity evaluation function and electronic image to determine the clarity of the optical system. The invention has a better scope of application, and the test result has higher accuracy and reliability.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a method and device for testing the clarity of an optical system. Background technique [0002] Among the evaluation indicators of the imaging quality of optical imaging equipment, the optical clarity of the imaging result is one of the important indicators. Therefore, the test of optical clarity is an indispensable step for evaluating optical equipment. [0003] In the prior art, the sharpness evaluation function can be used to evaluate the imaging sharpness of the optical device, and various sharpness evaluation functions are used to calculate the imaging results of the optical system to calculate the corresponding sharpness value. The main advantage of this method is that the system is simple and the amount of calculation is small. [0004] For the methods of testing the sharpness of the optical system with various sharpness evaluation functions, the core image processing al...
