Single-shot off-axis full-field optical coherence tomography

Abstract

Full field optical coherence tomography (FF-OCT) enables high-resolution in-depth imaging within turbid media. In this work, we present a simple approach which combines FF-OCT with off-axis interferometry for reconstruction of en-face images. With low spatial and temporal coherence illumination, this method is able to extract an FF-OCT image from only one interference acquisition. This method is described, and the proof-of-concept is demonstrated through the observation of scattering samples such as organic and ex vivo biomedical samples.
