Super-Resolution Imaging and Sensing with Relative Motion in Structured Illumination and Multiply-Scattered Light
Abstract
Optical sensing and imaging offers the possibilities of high resolution and object material information but is compromised by the scattering background that commonly occurs in terrestrial application. This project draws upon a possible scattering background as an enabler of a new paradigm for optical sensing in and through opaque media with high spatial resolution. The work builds on discoveries in the Webb group of a means for statistical imaging through unprecedented amounts of background scatter and, remarkably, access to the nanostructure, all based on the concept of relative motion in structured illumination, notably with speckle associated with coherent laser light. The two tasks each involve fundamental advances- (i) Fundamentals of Super-Resolution Sensing; and (ii) Macroscopic Object Imaging. The theoretical, simulationbased, and experimental efforts planned draw upon special facilities in the Webb group, including a fog chamber. New high-resolution sensing capabilities for the Air Force and Space Force will ensue from the fundamental work to be pursued.
