[0046] The implementation process of the present invention is given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0047] 1. Basic concepts
[0048] The typical optical path for single-pixel imaging is figure 1 Shown. The light emitted by the light source reaches the spatial modulator (Digital Micromirror Device, DMD) after being expanded by the lens. The DMD is composed of an independently programmable micro lens array. Each micro lens can be flipped in two directions to perform binary modulation. Load the random 0 / 1 measurement matrix on the DMD to achieve binary random modulation of the incident light field. The modulated light from a reflection direction of the DMD reaches the target through the lens, and is collected and detected by the barrel detector through the lens after the target is transmitted, and an element value of the detection value y can be obtained.
