Towards a Real Time Sensor for Focusing Through Scattering Media

Materials such as milk, paper, white paint and biological tissue scatter light. As a result, transmitted light intensity through these materials is a speckle pattern, having often a short persistence time. Recently, advances in optics to control light through disordered media have reported an increasing efficiency. Consequently, that allows us to foresee a real time sensor that achieve such task in an integrated way. Thereby, in this perspective, we propose a genetic algorithm implemented with pyramidal approach in a CMOS image sensor, which matches integrated data processing and short persistence time. Our algorithm have been simulated with a faithful model. Results show at least a gain of a factor 10 compared to the state of the art algorithms.
