Embodiment Construction
[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 of single-pixel imaging is as follows: figure 1shown. The light emitted by the light source reaches the digital micromirror device (DMD) after being expanded by the lens. The DMD is composed of an independently programmable microlens array. Each microlens can be flipped in two directions to perform binary modulation. By loading the random 0 / 1 measurement matrix on the DMD, the binary random modulation of the incident light field can be realized. The modulated light from a reflection direction of the DMD reaches the target through the lens, and after being transmitted by the target, it is collected and detected by the barrel detector through the lens, and an element value of the detection value y can be obtained.
