Tomographic Diffractive Microscopy: Development and Applications

Type d’annonce: Proposition – Thèses

Description de la proposition:

Optical microscopy techniques are among the preferred methods for biological studies thanks to their unique capability of imaging living specimens in 3-D. Tomographic diffractive microscopy (TDM) is a new technique [1], combining microholography with tomographic acquisitions. The MIPS laboratory develops this technique in transmission [2-5], in reflection [6,7], and with specimen rotation [8,9].

Our research project now aims at:
– further improving the resolution, in order to obtain an isotropic 3-D resolution in the 100 nm range for non-fluorescent specimens,
– developing new tomographic reconstruction methods, to expand the domain of applicability of TDM (Rytov approximation, complex field deconvolution)
– testing the instrument for biological investigations.
The selected candidate will join an active and recognized research group. Competences in optics/photonics, and/or image processing/instrumentation/computer sciences are necessary.
First, the high-resolution tomographic systems at MIPS will be upgraded. Theoretical and experimental work will be carried out in-home, to test new reconstruction methods. Work on biological samples will be performed through collaboration with IGBMC in Strasbourg (Dr Marc Ruff’s team), with help of a post-doc student to be recruited on the same topic.
Standard Fellowship: 1 684,93 €/month.
