abstract

  • revised December 1, 2011; accepted December 12, 2011; posted December 12, 2011 (Doc. ID 157141); published February 3, 2012 We developed an ultrahigh-resolution full-field optical coherence tomography (FF-OCT) microscope that is based on the spatial, rather than the temporal, coherence gating. The microscope is capable of observing three-dimensional microbiological structures as small as 0.4/4m x 0.4/4m x 1.0 14m (xyz) using quasi- monochromatic light and a liquid crystal retarder. Unlike traditional FF-OCT systems, this microscope can be operated in high resolution for any preferable wavelength with minimized defocusing and dispersion effects. High-resolution images of an onion cell are presented.© 2012 Optical Society of America
