Embodiment Construction
[0024] like figure 1 , the single-photon polarization quantum imaging system based on the DMD micromirror array of the present invention includes a laser emitting device 1 , a single-photon preparation system 2 , a DMD-controlled imaging device 3 , and an EMCCD imaging receiving system 4 .
[0025] like figure 2 , the single photon preparation device is composed of a spatial filter 5 , a neutral density filter 6 , and a half-wave plate 7 . The laser beam is emitted from the semiconductor laser, and undergoes spatial filtering and multi-stage attenuation through the spatial filter 5 and several neutral density filters 6 . A semiconductor laser with 100μW power emits λ=780nm laser light with an attenuation of 10 6 can reach the single-photon level. The single photon pulse directly acts on the half-wave plate, and the polarization state of the photon is switched into four directions: horizontal, vertical, diagonal, and anti-diagonal by controlling the half-wave plate.
