Internship M2-PFE "Optical coherence microscopy for biomedical diagnosis of the cornea"
13-01-2022 - Internships

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.

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.
