Master's degree training period: functionalized Tomographic Diffraction Microscopy - IRIMAS/Université de Haute Alsace (Mulhouse)

Catégorie : Stagiaire

IRIMAS Institute developed a Tomographic Diffraction Microscope (TDM) allow for full 3D-imaging of microscopic transparent samples, with an unequalled resolution (Opt. Lett. 34, p. 79 (2009), Optica 4, p. 460 (2017)).

Data acquisition consists of two steps:
1) The recording step, which consists in the acquisition of holograms of the sample under various illumination angles. This step being performed using an optical set-up designed at IRIMAS.
2) The reconstruction step consists in the extraction of wavefronts from the recorded holograms. These wavefronts are then combined to reconstruct the final 3D image.

These steps make it possible for 3D refraction and absorption characterization of the investigated sample. Nevertheless, it is possible to add new functionalities to the existing technique, without sample staining.
Within the framework of THTTM ANR funding (https://anr.fr/Projet-ANR-19-CE42-0004), we propose to explore the capabilities of TDM to operate in Doppler regime (see e.g. Opt. Express 22, p. 9368 (2014)).

Within this framework, the trainee will have to:
1) Become familiar with TDM data acquisition and reconstruction.
2) Participate in the finalization of the Doppler sensitive TDM device.
3) Perform first acquisitions on purpose designed microfluidics chips.

Expected skills: autonomy, resourcefulness, creativity. Strong analytical skills, as well as computational skills are mandatory.
Duration: 4 to 6 months
Gratification: 546 €/month (35h/week - 4 week/month basis)
