From: Lossy and noisy channel simulation in computational ghost imaging by using noise-induced pattern
Experimental setup for CGI with two targets used for imaging, 3 bars and alphabet A. An H-polarized laser beam is reflected at the phase-controlling SLM. The phase-modulated beam becomes an intensity-modulated beam after the PBS. The modulated beam illuminates a target object and the intensity of received light from the target is measured by using a single-pixel bucket detector. For channel-simulated imaging, noise source is turned-off and noise-added patterns are displayed on the SLM. For the verification of our channel simulation, we turn on the thermal noise source consists of a laser and a rotating ground glass disk, and we conduct the imaging with the original Hadamard patterns.
