Abstract : Optical coherence tomography (OCT) is a well-established optical imaging technique that uses low-coherence interferometry to produce micrometer-scale resolution images of biological media. Since its first application in examination of pathologic changes of the retina morphology, the range of applications of OCT has largely increased especially in the biomedical field. Full-field optical coherence tomography (FF-OCT) was introduced a few years ago as an alternative method to conventional OCT using an interference microscope and a camera as an array detector combined with a low coherence illumination source for parallel acquisition of en-face oriented tomographic images. However, FF-OCT is not very suitable for imaging high-scattering media (for which the penetration depth is quite limited) and for imaging in vivo sample (because of the low acquisition speed). In this work, we report different improvements that we bring to the former FF-OCT setup, in order to overstep those limitations.
