Ultrasensitive Multi-Octave and Multi-dimensional Spectral Sensing by Single Element Detection and Compressive
Abstract
The goal of the proposed work is to develop sensingtechnology that exceeds the state-of-the-art (SoA) for rapid identification and analysis ofcomplex chemical and biological targets. To accomplish this we propose to~ Use SPARSE spectroscopy, which involves combining spatiotemporal maps of space andtime with rapid digital micromirror device technology, to encode the nonlinear spectralresponse of complex molecular systems.~ Significantly exceed the information content of the current state-of-the-art (SoA) for rapididentification and analysis of complex chemical and biological targets throughmultidimensional nonlinear methods that reveal quantum signatures.~ Demonstrate the versatility of SPARSE for active standoff detection in harsh or erraticenvironments with high sensitivity and specificity. Specifically, SPARSE is capable ofeliminating background signals originating from light absorption, emission, or scattering,which obscures the target sensing.
