L1, L2, L3 and L4 are optical lenses whose focal lengths are 80 mm, 80 mm, 80 mm and 40 mm respectively. P1 is a horizontally polarized linear polarizer, and P2 is a vertically polarized linear polarizer. BS1 and BS2 are beam splitters. DMD is a digital micro-mirror device to display mask patterns. SLM is a spatial light modulator to display the object patterns. An sCMOS camera is used as the bucket detector by integrating all the pixels of each acquired image to produce the single-pixel signal.
