Abstract

We demonstrate an alternative yet effective approach for spatial gating without mechanical pinhole scanning. We take advantage of the intrinsic property of the robust self-interference effect of low-coherence enhanced backscattering under low spatial coherence illumination. The unique combination of low spatial coherence illumination and differential angle imaging permits the implementation of multiple independent virtual pinholes into a large area imaging platform. Thus, our imaging approach 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.
