Abstract

Multiple scattering is a significant obstacle in the optical imaging of biological samples. However, it is possible to reverse its effects through optical phase conjugation (OPC) of the scattered field. We perform digital OPC (DOPC) utilizing a spatial light modulator (SLM) and a Sagnac interferometer geometry. This design permits a simple and robust DOPC implementation, which we demonstrate experimentally. We exploit the beam-shaping flexibility of the SLM to demonstrate the possibility to enhance either the optical power transmission or the light focusing ability of the DOPC process.
