Embodiment Construction
[0021] The present invention proposes a first-photon laser imaging system based on photon marking, such as figure 1 It includes a photon encoding system 1, a 1×N laser array 2, an optical path deflection element 3, a two-dimensional scanning device 4, a telescope optical system 5, a beam focusing element 6, a photon decoding system 7, and a 1×N single-photon detector array 8. Multi-channel time-correlated single-photon counting system 9 and control and data acquisition system 10, wherein photon encoding system 1 and 1×N laser array 2 form a single-photon pulse light source that emits marking information; photon decoding system 7 is placed in the beam At the focal plane of the focusing element 6 , before the single photon detector array 8 , the single photons carrying different label information are spatially separated. The control and data acquisition system 10 is developed into a software package to run on the computer, and sends instructions to the photon encoding system 1 t...
