Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] Modulation transfer function (MTF) is an important performance parameter of visible light detectors, which has a decisive impact on the performance of systems using visible light detectors. Therefore, it is of great significance to test the modulation transfer function of visible light detectors.

[0016] A test system for visible light detector MTF and anti-diffusion test, such as figure 1 , including: darkroom 2, optical imaging system 3, mobile platform system 4, display and control terminal system 1. The optical imaging system 3 and the mobile platform system 4 are arranged in the dark room 2 , and both the optical imaging system 3 and the mobile platform system 4 are connected to the display and control terminal system 1 . The optical imaging system 3 can image the test target to the visible light detector under test. The mobile ...

Abstract

The invention discloses a test system for MTF and anti-dispersion test of a visible light detector, which relates to the technical field of optical system image detectors, solves the technical requirements of the existing MTF test system for highly integrated automation, and comprises a darkroom, an optical imaging system, a mobile platform system and a display control terminal system. The optical imaging system and the mobile platform system are both located in the darkroom and are both connected with the display control terminal system; the optical imaging system can image the test target to the to-be-tested visible light detector; the mobile platform system can move the to-be-tested visible light detector placed on the mobile platform system so as to realize imaging of a test target to the visible light detector; the display control terminal system can control the optical imaging system and the mobile platform system to work, can receive image data of the to-be-tested visible light detector, and can calculate the MTF and anti-dispersion capability of the tested visible light detector. Detection precision and multiple functions are guaranteed, the size is reduced, and the requirement for the external environment is not high.

Description

technical field [0001] The invention relates to the technical field of optical system image detectors, in particular to a test system for MTF and anti-diffusion tests of visible light detectors. Background technique [0002] The most notable features of the existing domestic and foreign MTF testing instruments are high precision and various functions, but they also have their shortcomings, such as: the structure of the multifunctional MTF measuring instruments is complex and bulky, the overall occupation area is large, and the experimental measurement data is limited. The time is long, the adjustment before and during the experiment is complicated, and the price is expensive. Most single-function MTF test instruments are simple in structure, but require a higher experimental environment to adapt to it, and even require other components to isolate the airflow to improve test accuracy. The maintenance is very low and the cost is high. Contents of the invention [0003] In o...
