(a) A schematic diagram of CGI under a lossy and noisy channel. Starting from a light source with intensity \(I_S\), the intensity of the initially patterned light is \(I_P = \int _A \frac{I_S}{A} P_S(\vec x)d\vec x\), and that of environmental noise is \(I_{B}/(1-\kappa )\). The two beams are mixed at a beam splitter whose reflectivity is \(\kappa\), and the mixed beam illuminates the target. The reflected beam intensity is measured at the detector. (b) A schematic diagram of CGI with noise-induced patterns. The beam modulated by a noise-induced pattern (\(P_T\)) illuminates the target, while the original pattern (\(P_S\)) is used for the image calculation. \(P_T\) is programmatically generated to have the same effects of noise and losses.
