摘要:
An optical system and associated method enable near real time optical phase conjugation. In the method, a translucent medium is illuminated by a sample illumination beam. Light scattered by the medium is directed to an electronic image sensor while a reference beam is also directed to the electronic image sensor. The scattered light and the reference beam form an interference pattern at the electronic image sensor. A digital representation of the interference pattern is recorded using the electronic image sensor, and the characteristics of a conjugate of the sample beam are computed from the numerical representation. A conjugate beam having the computed characteristics is generated using a configurable optical element and directed back to the translucent medium. The generation of the conjugate beam may be accomplished using a spatial light modulator.
