Optical sectioning using a digital Fresnel incoherent-holography-based confocal imaging system

Optica. 2014;1(2):70-74. doi: 10.1364/OPTICA.1.000070.

Abstract

We propose a new type of confocal microscope using Fresnel incoherent correlation holography (FINCH). Presented here is a confocal configuration of FINCH using a phase pinhole and point illumination that is able to suppress out-of-focus information from the recorded hologram and hence combine the super-resolution capabilities of FINCH with the sectioning capabilities of confocal microscopy.
