High-resolution optical correlation imaging in a scattering medium

Opt Lett. 2001 Dec 15;26(24):1969-71. doi: 10.1364/ol.26.001969.

Abstract

An optical correlation setup is used to image transparent objects through scattering media, and 10-mum longitudinal and 2.5-mum transverse resolution are achieved. Spectral-bandwidth sampling of the light source is made possible by a tunable dye laser and leads to signal enhancement as a result of sampling interferogram filtering. An optical system allows observation of sample slices without the need for a translation stage.
