Abstract

We present that multiple mutually independent coherence areas can be used for simultaneous spatial filtering in an imaging platform as effective as pinhole scanning. In this imaging platform, the unique combination of low-spatial-coherence illumination and differential angle imaging allows us to take advantage of low-coherence enhanced-backscattering (LEBS) phenomenon to permit self-generated optical sectioning to the subsurface in a relatively large area. We further demonstrate that LEBS spectroscopic imaging substantially minimizes cross talk among adjacent pixels, rejects the background light caused by out-of-plane scattered light, and thereby enhances image contrast and resolution.
