Abstract

We have used Full Field OCT (FFOCT) in its static (morphology contrast) and dynamic (metabolic contrast) modes mostly for tissue diagnosis. Last year we introduced a new way of optical sectioning 3D structures. For this purpose, we use Full Field Optical Transmission Tomography (FFOTT) a Gouy phase shift interference approach that takes place close to the focus of a microscope objective. We will show striking differences between FFOCT and FFOTT associated to the scattering anisotropy of tissue structures. Moreover, we will pay a particular attention to the requirements of FFOTT in term of spatial coherence and to the speckle appearance for both techniques.
