Abstract

A degraded fluorescence image passing through a weak diffuser is improved by the acquisition of fluorescence wavefront information and phase retrieval. The amplitude and phase distributions of the fluorescent light wave are obtained using the transport of intensity equation. After calculating back-propagation to the diffuser surface from the recording plane, phase retrieval is applied for improving the image quality. Experiments using fluorescent beads examined at different recording plane showed the effectiveness of the proposed method.
