Abstract:
A new instrument paradigm is proposed based on the discovery of a method to
determine a robust inverse point spread function for a scientific observing
instrument modeled as a linear system. As a result of this discovery, it is
possible to contemplate an instrumental extension which results in the recovery
of a major portion of lost resolution due to the blurring effects of the PSF.
Implementation of the instrumental extension and the resulting resolution
enhancement is independent of prior knowledge of or access to the observed
data. The method is applied to HST images as well as several one dimensional
spectral data sets. Results of HST recoveries are compared to Richardson-Lucy
recoveries.
