Project Introduction

A Lightweight Compact Multi-Spectral Imager Using Novel Computer-Generated Micro-Optics and Spectral-Extraction Algorithms
The objective of this NASA Early-stage research proposal is to demonstrate an ultra-compact, lightweight broadband hyper- and multi-spectral imaging system that is capable of (1) detecting near-Earth objects (NEOs), (2) determining the size of NEOs, (3) determining the rotational characteristics of NEOs and (4) characterizing the material composition and thereby, determining the mass of NEOs. We achieve these goals by utilizing a novel broadband diffractive-optic to disperse incident light, collecting the dispersed image, and then by using new algorithms to reconstruct the incident unknown spectrum.
