Bessel light-sheet microscopy: object adapted illumination and opto-genetic switching with computer holograms

Job offer from January 15th, 2020

In a project funded by the new excellence cluster CIBSS (University of Freiburg), the lab for Bio- and Nano-Photonics seek a physicist or engineer to continue and extend our research on light-sheet microscopy using scanned holo-graphically shaped Bessel beams.  

Your tasks

In this project, we will extend/develop a light-sheet microscope, which will be equipped with two spatial light modulators (SLM) for high-end 4D imaging of large, scattering specimen and for precise opto-genetic switching with either blue light or pulsed NIR light. Unprecedented image quality will be achieved by using holographically shaped, object adapted, confocal Bessel beams for imaging various samples provided by the collaboration partners. By a novel postprocessing method, we are able to separate diffusive and ballistic photons, which leads to a high image quality also deep inside the specimen. By developing a feedback controlled, holographic multipoint laser illumination through the second SLM, we will realize dynamic and precise opto-genetic switching in large specimen with superior precision and efficiency.
