Abstract

The moderate resolution imaging spectrometer (MODIS) is an earth-viewing sensor that is planned as a facility instrument for the Earth observing system (Eos) scheduled to begin functioning in the late 1990s. The MODIS is composed of two mutually supporting sensors, one of which is MODIS-T (where ''T'' signifies a tiltable along-track field of view). MODIS-T is a 32-channel imaging spectrometer with a required 10 nm to 15 nm spectral resolution (FWHM) in the 400 nm to 880 nm spectral range with less than 2.3 instrument-induced linear polarization. At nadir the instrument provides a 33 km by 1500 km swath with a 1.1 km spatial resolution and an along-track pointing capability of +/- 50 degree(s). The heart of the optical design consists of a f/3 grating-type reflecting Schmidt camera.
