Job description:

A DMD, “digital micromirror device”, is a micro-opto-electro-mechanical system consisting of upto 8 million micromirrors used in projector systems. Each mirror can be tilted individually to modulate the light to generate complex illumination patterns. The goal of this project is to use a DMD as an optical excitation for studying photo-sensitive bacteria. The light pattern from the DMD is coupled to a multi-mode fiber (MMF) of 50-micron core diameter. By varying the patterns projected on the DMD, the light at the distal end of the fiber can be focused to a 3 µm spot. Genetic optimization algorithm can be used to identify the phase pattern that generates the focused spot. The hardware control of the processor and the camera and the algorithms will be implemented using Python programming.


The specific tasks within the project will be: (i) Embedded system programing; (ii) Genetic algorithm implementation using Python threads; (iii) Testing and optimization of the code in the optical setup to obtain the focused; (iv) Design and fabrication of 3D parts.


You will be integrated in a larger team within the SPA-Lab. This is a complete project, offering the possibility to handle embedded system and optics and test the measurement setup, giving you the opportunity to co-author conference and/or journal publications.
