Optical Implementation of Matching Pursuit for Image Representation

Chao, T.; Lau, B.; Miceli, W. (1994)

We have developed a technique for image analysis, representation, and decomposition. This technique was motivated by Stephane Mallat's matching-pursuit algorithm. We've altered and simplified the mechanics of his algorithm ...

optical Instruments for Remote Sensing from Space

Chrisp, Michael P. (1992-11)

This review covers the optical design of passive remote sensing optical instruments. The review concentrates on the design of spaceborne multispectral cameras and imaging spectometers. The major designs that have been ...

Optical Interferometry from the Lunar Surface

Rayman, Marc D.; Saunders, R. S. (1995)

A preliminary study was conducted to dertermine the feasibility of a concept for a

Optical interferometry motivation and history

Lawson, Peter (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-07-24)

Optical landmark detection for spacecraft navigation

Cheng, Y.; Johnson, A. E.; Matthies, L. H.; Olson, C. F. (2003-02-09)

In this paper, a new crater detection algorithm is suggested. Experimental studies show that this new algorithm can achieve sub-pixel accuracy in position, its detection rate is better than 90% and its false alarm rate ...

Optical links and RF distribution for antenna arrays

Huang, Shouhua; Calhoun, Malcolm; Tjoelker, Robert (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-06-05)

An array of three antennas has recently been developed at the NASA Jet Propulsion Laboratory capable of detecting signals at X and Ka band. The array requires a common frequency reference and high precision phase alignment ...

Optical measurements of gravity fields

Maleki, L.; Yu, N.; Matsko, A. (2003-01-05)

Optical measurements of a gravitational field with sensitivity close to the sensitivity of atomic devices are possible if one detects properties of light after its interaction with optically thick atomic cloud moving freely ...

Optical metrology for Starlight Separated Spacecraft Stellar Interferometry Mission

Dubovitsky, S.; Lay, O. P.; Peters, R. D.; Abramovici, A.; Asbury, C. G.; Kuhnert, A. C.; Mulder, J. L. (2002-10-29)

We describe a high-precision inter-spacecraft metrology system designed for NASA 's StarLight mission, a space-based separated-spacecraft stellar interferometer. It consists of dual-target linear metrology, based on a ...
