Goal of the project

How should light be structured to extract the maximum amount of information from scattered light? This postdoctoral project aims to answer this question by developing a new generation of imaging methods combining wavefront shaping, information theory, and computational optics. 

Project description

Wavefront shaping has transformed our ability to control light propagation through scattering systems. Using programmable optical devices such as digital micromirror devices (DMDs), it is now possible to engineer optical fields with high speed and focus light behind or inside complex media [1]. Yet a central question remains open: How should one shape light to make images with optimal precision?

We propose to answer this question using tools from statistical estimation theory, and in particular the Fisher information, which quantifies the ultimate precision achievable in parameter estimation [2]. Building on previous work demonstrating the existence of structured light fields that maximize the Fisher information [3], the project will extend these concepts from single-parameter estimations to the reconstruction of high-dimensional images involving many unknown degrees of freedom.
