Abstract
The invention relates to a system (20) for full-field interference microscopy imaging of a three-dimensional diffusing sample (206). Said system includes: —an interference device (200) including a reference arm on which a reflective surface (205) is arranged, the interference device being suitable for producing, at each point of an imaging field when the sample is placed on a target arm of the interference device, interference between a reference wave, obtained by reflection of incident light waves onto a basic surface of the reflective surface (205) corresponding to said point of the imaging field, and a target wave obtained by backscattering of incident light waves by means of a voxel of a slice of the sample at a given depth, said voxel corresponding to said point of the imaging field; —an acquisition device (208) suitable for acquiring, at a fixed path length difference between the target arm and the reference arm, a temporal series of N two-dimensional interferometric signals resulting from the interference produced at each point of the imaging field; and —a processing unit (220) configured to calculate an image (IB, IC) representing temporal variations in intensity between sa…
