Stage M2 : Design of advanced meta-cameras for augmented imaging in nanophotonics and cell biology

Keywords : Optical microscopy, augmented imaging, nanophotonics, cell biology

Standard cameras transform a rich optical 3D scene, featuring intensity, polarization, color and phase
information, into a poor 2D intensity image, discarding most of the important information. Optical
elements, such as micropolarizer arrays, microfilter arrays, metasurfaces, 2D gratings, complex media,
or microlens arrays, can be placed at the close proximity of the camera sensor to retrieve all this missing
information, in a single-shot image acquisition.

The master project will consist in integrating several of these optical elements at the close vicinity of a
camera sensor, and implement it in a high-resolution optical microscope to characterize nano- and
micro-objects, such as live cells in culture (cancer cells, neurons, etc), tissue, micro-organisms (bacteria,
phytoplankton), nanoparticles, 2D materials, or metasurfaces.

This Master’s internship could lead to a CIFRE PhD thesis.
