Abstract

We describe a new technique of space based spectral imagery for a spinning platform. The technique uses tomographic inversion to produce a 2D spectral image using a novel imaging spectrograph. The spectrograph uses a single optical element with a large field of view. Our technique delivers high throughput due to continuous observation of the scene at all wavelengths. The challenge of spectral imaging is to obtain 3D information from a time series of 2D data. In our technique, we obtain spectral information along one detector dimension, while two dimensions of spatial information are combined into the second dimension of the detector for each time step. With the spin axis of the spacecraft located at the center of the scene, we recover the 2D of spatial information from a series of these individual 'snapshots'. We will report on the results obtained on May 8, 1997 by a sounding rocket experiment using this technique in the 80- 140nm wavelength range, on the Scorpio constellation.
