Abstract:
An optical phase processing system for a scattering medium. A first beam has a direction and a wavefront and the first beam is configured to enter a holographic recording medium. A scattering medium is illuminated by a signal beam generating at least one scattered beam. An interference pattern is recorded from the at least one scattered beam and the first beam. A second beam is generated in a direction opposite to the direction of the first beam, the second beam having a wavefront and a phase substantially opposite to a phase of the wavefront of the first beam, and the second beam is configured to enter the holographic recording medium. The second beam and the interference pattern interact to generate at least one reconstructed beam having a phase substantially opposite to a phase of the at least one scattered beam, and the at least one reconstructed beam is configured to be viewable through the scattering medium.
