Abstract

The invention relates to a scientific-level CMOS camera performance test system and method, and the method comprises the following steps that 1, a user interface module receives the input of a user, and transmits the input of the user to a flow control module in a request mode; and 2, the flow control module analyzes the request of a user, calls a corresponding test script, controls, by calling aninterface of a uniform light source system to a to-be-tested camera, the to-be-tested camera and the uniform light source system to realize refrigeration, set a configuration value, control exposureintensity and exposure time, perform imaging, and perform specific test, including an FPN test, a dark current test, a gain, noise, response linearity and full well capacity test and a dead pixel test. Characteristics of the scientific-level CMOS camera are fully considered, the corresponding test flow is designed for performance indexes of the scientific-level CMOS camera, and a complete test scheme can be provided for testing of the scientific-level CMOS camera. On the premise that the design of the test scheme is errorless, the test flow can be automatically executed, and the workload of research and development personnel is extremely effectively reduced.

Description

technical field [0001] The invention relates to the field of performance testing and control systems of scientific-grade CMOS cameras, and specifically refers to a set of testing systems capable of automatic testing of scientific-grade CMOS cameras. The system as a whole adopts the method of software and hardware collaborative design for architecture, and designs four sets of complete procedures for testing different performance parameters of scientific-grade CMOS cameras, which can assist R&D personnel to make systematic judgments on various performance indicators of the camera, and pass The test system realizes the automation of the test process, which can greatly reduce the workload of R&D personnel. Background technique [0002] Scientific-grade CMOS cameras are widely used in scientific research fields such as space observation, biology and high-energy physics. When developing a scientific-grade CMOS camera, R&D personnel need to test the camera to obtain various perfo...
