Light Curve Inversion for Characterization of Objects with Concavities
Abstract
In this contract, we explored new techniques for the light curve inversion for shape. In the course of the contract, two techniques were fully developed and led to successful results. Light curve inversion using the Extended Gaussian Image has been significantly extended to be fast and reliable for shape inversion in the presence of noise. Here, the work of Dr. Oliker was further developed. A new technique has been developed to invert light curves and find objects with a concavity. It is the first of its kind to find shapes with concavities. Independent of this first inversion approach, compressed sensing has been explored for inversion, not creating 3D shape models but resolved images from the light curve. It is also the first technique to explore light curve inversion under this approach.
