En-face optical coherence tomography

Utility and modalities of producing en-face optical coherencetomography (OCT) images of the tissue are discussed. Using a versatile system, transversal and longitudinal OCT images from the retina and skin are presented. Using stacks of transversal OCT images, 3D profiles of the tissue are constructed. The stack of en-face OCT images could also be used to infer longitudinal OCT images. These are compared with the longitudinal OCT images produced with the OCT operating in the hardware longitudinal regime. Once en-face OCT images are produced, they could easier be compared with confocal images as their orientation is similar. Images from the optic nerve are shown generated with the two technologies implemented in a stand-alone system
