Problems solved by technology

However, the low-light ICCD resolution is related to the coupling effect of the low-light image intensifier and the CCD device. This method does not truly and accurately reflect the influence of the coupling effect of the low-light image intensifier and the CCD device on the low-light ICCD resolution. A complete evaluation of low-light ICCD resolution cannot be achieved
[0005] At present, there are no relevant reports on the measurement device and measurement method for the comprehensive evaluation of low-light ICCD resolution.

Abstract

The invention puts forward a low-light ICCD resolution measuring device and a measuring method, and belongs to the field of optical measuring and metering. The low-light ICCD resolution measuring device is characterized in that the low-light ICCD resolution measuring device is constructed with a light source system, a resolution target, a conjugate lens group, a measurement camera obscura, a video image acquisition system and a computer, wherein the conjugate lens group images the resolution target irradiated by the light source system and projects the resolution target to a measured low-light ICCD, the video output line of the measured low-light ICCD is connected to the video image acquisition system, the video image acquisition system acquires a resolution target image output by the measured low-light ICCD and sends the resolution target image to the computer, and the computer is used for displaying the resolution target image transmitted by the video image acquisition system. The problem of low-light ICCD resolution measurement is solved. The measuring device and the measuring method can be extended to EMCCD resolution measurement and other fields in need of establishment of a resolution measuring device and research of a resolution measuring method, and have a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of optical measurement and measurement, in particular to a low-light ICCD resolution measurement device and a measurement method. Background technique [0002] Low-light ICCD is a photoelectric imaging system formed by coupling a low-light image intensifier and a CCD device through a light cone or a relay lens. It has the advantages of high sensitivity and low-light imaging quality. An important device for electronic information output, which represents the development trend of low-light night vision equipment informatization and information sharing, and is the core device of a new generation of low-light night vision equipment. The accurate measurement of low-light ICCD parameters plays an important role in promoting the further improvement of low-light night vision technology research. Resolution is one of the most important parameters of low-light ICCD, which reflects the ability of low-light ICCD to res...
