Recently, progress has been made in developing full-field optical coherence tomography (FF OCT) with the advantage of acquiring an <I>en-face</I> sectional image. Based on the Linnik interferometer, the FF OCT achieves an acquisition speed of 250 frames/s using a cw Xenon lamp and CMOS camera to measure OCT images of rat eye <I>in vivo</I>. We have been studying quadrature-fringes full-field OCT (QF FF OCT) to measure the 3D images and to sense the activity of rat cortex. QF FF OCT enables acquiring the <I>en face</I> sectional image with only two exposures. The principle of QF FF OCT and the 3D OCT images (4mm×4mm×2.9mm depth) of <I>in situ</I> rat cortex are introduced.
