Abstract

Fourier-domain full-field optical coherence tomography (FD-FF-OCT) is currently the fastest volumetric imaging technique that is able to generate a single 3D data volume in less than 10 ms. FD-FF-OCT is based on a fast camera, a rapidly tunable laser source and a Fourier-domain signal detection. However, crosstalk corrupts images with speckle and therefore lowers image quality. Corneal imaging with FD-FF-OCT is also challenging since the laser focuses down on the retina causing safety concerns. We present spatially incoherent FD-FF-OCT system that reduces crosstalk noise in retina images and enables corneal imaging by reducing spatial coherence of the laser.
