Research on high sensitivity test technology of single photon remote detection system

In this paper, the test environment of all-state single-photon remote detection system established in the laboratory is introduced. In this environment, a noise-free test environment is established, and a quantitative measurement device is established for the sensitivity test of the single-photon receiving system, and the sensitivity test can be carried out without background noise and background noise so as to verify the compliance of the design. And a dynamic target algorithm verification environment is established to test the single-photon dynamic algorithm. The test system is matched with a narrow line-width high-repetition frequency test device, and basically can test the main performance indexes of single-photon, and provides technical support for the design and development of a single-photon remote test system.
