Abstract

1. A full-field optical coherence tomography imaging method, FFOCT, using a system comprising an FFOCT device and a sample, the sample comprising a layer of interest (115) to be imaged, the FFOCT device comprising an incoherent light source (101), an imager (114), a beam splitter (103) defining a sample arm (107) and a reference arm (108), the method comprising - generating sample light containing interest light originating from the layer of interest and reference light traveling from the reference arm (108), - acquiring an image from reference light and sample light combined in the beam splitter (103); wherein at least one of the sample arm (107) and the reference arm (108) comprises an optical curvature compensator that modifies a transverse variation distribution of an optical path length to match the transverse variation distributions of the optical path lengths travelled by the reference light and the interest light incident on the imager (114).
