Full-field optical coherence tomography (FF-OCT) is a newly developed technique capable of acquiring a horizontal cross-sectional (<I>en-face</I>) image without lateral scanning. In this paper two configurations of FFOCT system are described. The first one employs a frequency-synchronous detection method that operates a pair of CCD cameras as the heterodyne detector arrays. A series of <I>en-face</I> images are thus acquired at the camera frame rate in a single longitudinal scan, making the fast acquisition of three-dimensional information possible. The second system is based on a Linnik microscope for optical coherence microcopy. Using a tungsten halogen lamp as the low-cost ultra-broadband source, sub-cellular imaging is demonstrated in biological objects.
