Paper Abstract

We describe the optical and mechanical design of a simple hand-held near infrared spectrograph constructed to produce observations of the spectrum of scrambled light from the Earth from aboard the International Space Station. Observing the Earth in this manner simulates the changing perspective on an extra-solar terrestrial planet observed as a point source by the Terrestrial Planet Finder. A Sensors Unlimited, Inc. SU320-M InGaAs(0.86 - 1.72μm) camera detects the dispersed spectrum and outputs NTSC video to be recorded and also permits frame grabbing. One of the three copies of the instrument is currently aboard the International Space Station. The optical and mechanical design was conceived and executed by graduate and undergraduate students at the University of Virginia.
