Special AMO/QO Physics Seminar

"Angular Momentum, Rotating PSF, and 3D Source Localization"

Dr. Sudhakar Prasad

Modern imaging systems are a far cry from the best imagers of the twentieth century. They gather, transmit, and process information in the most efficient manner, and are optimized for certain tasks, rather than visual image quality. The angular momentum of light can be exploited in the design of one such system that can acquire images of three dimensional (3D) sources in a single snapshot. I will describe and discuss the theoretical underpinnings of this novel design, and present a Bayesian error analysis to demonstrate its claim to perform 3D localization of point sources to super-diffractive, nanometric precisions using visible light.
