Abstract
Optical phase conjugation is a known technique for optically
reproducing an object behind a scattering medium. Here we present
digital optical phase conjugation through scattering media with
spatially and temporally incoherent light. This enables us to
eliminate the inevitable light coherence and the need for
interferometric measurement for optical phase conjugation. Moreover,
we show a method for suppressing background noise, which is critical
in incoherent optical phase conjugation. We numerically and
experimentally demonstrate the proposed method with background
suppression.
