Abstract :
We present an overview of the performances of a plenoptic microscope which combines the high sensitivity of a laser optical feedback imaging set-up, the high resolution of optical synthetic aperture and a shot noise limited signal to noise ratio by using acoustic photon tagging. By using an adapted phase filtering, this microscope allows phase drift correction and numerical aberration compensation (defocusing, coma, astigmatism ..). This new kind of microscope seems to be well adapted to make deep imaging through scattering and heterogeneous media.
