Experimental setup. (a) In the recording step, the input beam (denoted as “INP beam”), which is spatially filtered through a single-mode fiber (SMF), propagates through the scattering media (S). The scattered input beam is then collected by the planoconvex lens (L, focal length = 5 cm) and relayed to the sCMOS sensor through a 1X telescope system (1X TS), interfering with the collimated reference beam (denoted as “REF beam”). The complex field distribution of the signal beam is then measured using a four-step phase-stepping method. (b) In the playback step, the collimated playback beam (denoted as “OPC beam”) reflects off the spatial light modulator (SLM) on which the conjugated phase of the measured wave front is displayed. The APD measures the fraction of power in the phase conjugate beam that is coupled back to the SMF, and the CCD camera directly captures the transmitted intensity distribution.
