Abstract

Optical coherence tomography (OCT) enables the measurement of the structural information of diffuse samples such as tissue in a non-invasive and label-free way, by retrieving a depth-resolved signal from the back-scattered part of the excitation light. In its original implementation, classically denoted as time-domain OCT, a three-dimensional scanning is required to retrieve an x-y image of the signal emitted by the back-scatterers at a certain depth z, with the signal being extracted from the interference pattern in depth.
