Abstract

This paper presents a novel approach for forward viewing endoscopy based on off-axis swept source full-field optical coherence tomography. In contrast to common OCT endoscope probes, based on side-viewing, we propose a design without electro-optical components, while still able to produce forward-view images. Here, through an analogous setup, we study the effect of the different free parameters of the design, such as input polarization state, off-axis angle, and beam divergence. As a result, we present B-Scans showing the OPD variation while changing the off-axis angle. Overall, we study the impact of the free parameters for optimal working conditions of the proposed endoscope.
