Abstract

Full-field Optical Coherence Tomography (FF-OCT) is a parallel detection OCT technique using a 2D detector array. This technique avoids mechanical scanning in imaging optics. Therefore, it can speed up the imaging process and enhance the imaging quality. We present a FF-OCT instrument to be used in conjunction with the principle of multiple delays (MD) OCT to evaluate the topography of curved objects in a single-shot imaging. We evaluate the optimum combination of the MD principle with the FF-OCT method and measure the radius of a metal ball with this method. We managed to obtain 2n-1 contour lines using an MDE with n delays in a single en-face OCT image to evaluate the curvature of the object surface.
