Abstract
A detector of light transmitted through a turbid medium, comprising: one or more Digital Optical Phase Conjugation (DOPC) devices, wherein the DOPC devices include (1) a sensor for detecting input light that has been transmitted through the turbid medium and inputted on the sensor; and (2) a spatial light modulator (SLM) for outputting, in response to the input light detected by the sensor, output light that is an optical phase conjugate of the input light.
