Fuse short-range target imaging system and method with high signal-to-noise ratio

The invention provides a high signal-to-noise ratio fuze short-range target imaging system and a high signal-to-noise ratio fuze short-range target imaging method in order to solve the problem that the accuracy and precision of fine detection and identification of a fuze short-range target are reduced due to low image signal-to-noise ratio in a strong noise environment. The system comprises a fundamental transverse mode semiconductor laser, a correlated photon pair generator, a narrow-band filter, a beam splitter prism, a signal retention device and a first charge coupling element, wherein the correlated photon pair generator, the narrow-band filter and the beam splitter prism are sequentially arranged on an emergent light path of the fundamental transverse mode semiconductor laser; the target object to be measured and the second charge coupling element are sequentially arranged on the transmission light path; and the data processing module is connected with the first charge coupling element and the second ch
