Paper Abstract
The terrestrial remote sensing community is interested in segmented aperture space telescopes with geometries
similar to NASA's James Webb Space Telescope (JWST). However, the unorthodox design has caused a decrease
in image quality introduced by piston, tip, and tilt phasing errors of the segments and lightweight mirror aberrations.
Traditionally image quality has been determined using the Generalized Image Quality Equation (GIQE),
however Fiete et.al.1 have shown that there are inherent problems with the GIQE method when working with
apertures that are not circularly symmetric. In this paper an image utility technique utilizing a multispectral
motion detection algorithm is used to show how changes in mirror phasing and varying degrees of lightweight
mirror aberrations affect a systems utility for detecting motion.
