Internship M2-PFE "Optical coherence microscopy for biomedical diagnosis of the cornea"

Master 2 or 3A Engineering School in physics/photonics/biomedical engineering

As part of a research project on the diagnosis of keratoconus and the detection of scars from refractive surgery, we have identified the benefit of providing the OCT microscope system (developed in the team, and with higher optical resolution than commercial systems (μm)) with polarimetric sensitivity. The main objective of the internship is therefore to complete the existing full-field OCT microscopy set-up to allow polarimetric contrast measurements on biological samples provided by medical partners. The components necessary for the project are already supplied (optics, cameras etc.). The trainee will therefore have to take charge of the existing OCT microscope and master the concepts of polarimetric imaging, then ensure the development of the instrumental system, its calibration and its validation. Finally, he / she will be responsible for developing the data / image processing methodologies, in close collaboration with the Ophthalmology Department of La Timone Hospital.

Place: Institut Fresnel & CERIMED, Marseille
Duration: 5 à 6 months
Fundings:  546 €/month
Supervisor: Julien FADE, MCF HDR, Ecole Centrale Marseille, équipe DIMABIO et Thierry DAVID, PU-PH, Service d’Ophtalmologie de la Timone, APHM.

Bi-modal super-resolved optical microscope (fluorescence and diffraction) for surface imaging of cell membranes.

Abstract :

The objective is to develop an optical microscope with sub-100 nm resolutin able to image simultaneously the fluorescence and the refractive index of the sample in order to combine the functional image with the structural one. This tool will be used to study the dynamics at the cell membrane.
