Ultrasensitive and Rapid Multi-Dimensional Spectral Sensing at Standoff Distances by Non-Uniform Sampling and Statistical Reconstruction
Abstract
ABSTRACT:The subject proposal, entitled ~Ultrasensitive and Rapid Multi-Dimensional Spectral Sensing at Standoff Distances by Non-Uniform Sampling and Statistical Reconstruction~, will develop a sensing technology that exceeds the state-of-the-art (SoA) for rapid identification and analysis of complex chemical and biological targets using a novel nonlinear coherent spectroscopy method that is far more sensitive to the chemical and physical structure of the target than traditional linear methods. Furthermore, non-uniform sampling and statistical reconstruction methods adapted for optical measurements will be developed to reduce acquisition times by 3-4 orders of magnitude. The PI, Prof. Elad Harel has extensive experience in the development of spectroscopic and imaging methods. During his PhD, Prof. Harel invented methods to image microscopic flow in microfluidic chips and nanoporous materials using non-invasive magnetic resonance methods. This work was featured in the high impact journals of Science, Nature Materials, and Physical Review Letters. Prof. Harel has continued to develop novel spectroscopic and imaging methods including super-resolution and sub-diffraction methods for tracking energy flow in complex molecular systems, such as pigment protein complexes and semiconductors. He has been awarded the prestigious Packard Fellowship for Science and Engineering in 2013, an ONR YIP, and a PECASE award through AFOSR. His research is strongly connected to US defense interests
