Background technique

The traditional ghost imaging system modulates the spatial light generated by the light source through an SLM (spatial light modulator, spatial light modulator) to obtain a modulated light source signal. The specific modulation process is controlled by a computer, and the modulated light source signal obtained after modulation is focused by a lens.
