Current projects include:
Passive Ranging: We have demonstrated a passive sensing technique to estimate range to an emissive target (such as boost-phase missiles) based on atmospheric absorption. Past demonstrations have used high-resolution measurements of an oxygen absorption band near 762 nm. Current efforts include exploring infrared absorption bands, which would enable passive ranging of a new class of targets, and evaluating smaller sensors to replace the large, complex spectrometers used in initial experiments.
Chromotomographic Imaging (CTI): This hyper-spectral imaging technique uses a rotationg prism to disperse light. Multiple camera frames (at multiple prism angles) are used to reconstruct a data hypercube using a tomographic process (similar to medical imaging). We are designing and testing a visible-band CTI system as risk-reduction for the CTEx space-based hyperspectral imaging experiment.
