Abstract

Imaging through a dynamic scattering medium produces low contrast image due to additional large background of scattered light. A passive phase conjugate mirror (PPCM) can generate an image with enhanced contrast. The background noise changes faster than the recording medium integration time and therefore is not recorded. This system does not require a reference wave coherent with the image and it operates in real time. Experimental results through a simulated scattering medium demonstrate contrast improvement over that obtained with conventional imaging arrangement.
