摘要	In order to measure the quantum efficiency of linear array image sensor (hereinafter referred to as linear array camera), a set of quantum efficiency measurement system based on focusing scanning method is established. A linear array CMOS camera is tested and the uncertainty of the test results is analyzed. Firstly, a test system composed of a lighting source, a monochromator, a scanning motion mechanism and a standard detector is built. Then the scanning motion mechanism is used to drive the linear array camera and the standard detector to move with high precision and uniform speed so that the camera can scan and image the generated monochromatic spot. By switching the position between the linear array camera and the standard detector, the energy of the monochromatic spot can be measured. Finally, the sum of gray scale of the images collected by the linear array camera and the sum of the light energy detected by the standard detector are analyzed and calculated. Combined with the theoretical formula of the focused scanning method, the quantum efficiency of the linear array camera is obtained. The test results show that the focusing scanning method is feasible for measuring the quantum efficiency of linear array camera, and the repeatability accuracy is high. By analyzing the uncertainty of the test results, the measurement accuracy of the quantum efficiency of this method is about 2.6%. Quantum efficiency measurement system for focused scanning linear array camera innovatively proposes the dynamic linear scanning focusing measurement of linear array camera quantum efficiency. This system is different from the traditional quantum efficiency test method for planar array camera that irradiated by monochromatic light combined with integrating sphere in principle, and makes up for the shortage of the linear array camera's quantum efficiency testing methods and low precision. In addition, the application of focusing scanning method to measure quantum efficiency is not limited to linear array cameras, but can also test photoelectric parameters of various types of cameras, and the measurement accuracy can meet the requirements of most projects.
