Compressive sensing

  • First, the imaging target is projected onto the DMD through the optical path system. The reflected light is focused by the lens onto a single photodiode. The voltage across the photodiode is a measured value X, this projection operation is repeated N times, and then the original image.
  • DMD by the digital voltage signal control micro-lens flip to achieve the adjustment of the incident light, the equivalent of 0-1 random measurement matrix
