Paper Abstract

Spatiotemporal optical coherence (STOC) imaging is a novel technique for suppressing coherent cross-talk noise in full-field swept-source OCT (FF-SS-OCT). In STOC, we use time-varying phase masks to modulate light incident on the sample. The modulated signals are averaged incoherently or coherently to yield cross-talk-free 3D images of the sample. We show that coherent averaging is only possible under specific hardware configuration. We explain this theoretically and confirm experimentally by imaging USAF chart covered by diffusers and the rat skin ex vivo. Finally, we present human forearm skin imaging in vivo. In all cases, STOC imaging reveals otherwise invisible sample features.
