Paper Abstract

The imaging spectrometer is a next-generation remote sensing sensor based on imaging spectroscopy and used as an Earth Observing System (EOS). It possesses the characteristics of both an imaging system and a spectral instrument and its output is the image-spectrum data. By virtue of the modulation transfer function (MTF) the effective instantaneous field of view (EIFOV) and effective spectral resolution (ESR) can be defined. Since these two resolutions correspond to the same criterion of MTF, the imaging spectrometer is different from the common multispectral scanner and its spatial and spectral resolutions are not independent. The relationship between the two resolutions and compromise principle are discussed in this paper.
