Abstract

This presentation discusses a new class of optical devices for observing the earth and its atmosphere that can be used to correct for the loss of image resolution due to earth curvature effects as you approach the edge of the earth disk as viewed from a satellite. These devices are primarily intended for use with two-dimensional CCD imaging arrays, including hyperspectral remote sensing systems viewing the earth from geostationary orbit. In this configuration they offer the possibility of uniform spatial resolution imagery extending across virtually the entire earth disk. The technology, however, can also be adapted to provide data with a uniform sensor resolution over broad sensing swaths using linear sensor arrays on satellites in low earth orbit, or from any of a variety of conical scanning instruments.
