Paper Abstract

We present a full-field optical coherence tomography system designed to produce high-resolution tomographic images in ultra-short acquisition times. The experimental setup is based on a Linnik interferometer illuminated by a tungsten halogen lamp. En face tomographic images are obtained in real-time without scanning by computing the difference of two phase-opposed interferometric images recorded by two high-resolution CCD cameras. Transverse resolution down to 1.6 μm is achieved by using high numerical aperture microscope objectives. Axial resolution, governed by the source coherence length, is 0.9 μm. 4x4 pixel binning leads to a detection sensitivity of ~ 65 dB. The rapid image capture of the cameras reduces acquisition time to 5 ms. The rapidity of our system makes it suitable for in vivo imaging of biological media, in particular the study of ultra-rapid biological phenomena.
