Instrument Requirements for a Next Generation 1km Resolution Hyperspectral Imaging Spectrometer

This slide presentation reviews the requirements expected from an instrument that combines the capabilities of the Atmospheric Infrared Sounder (AIRS) and the Moderate Resolution Imaging Spectroradiometer (MODIS). The types of products anticipated, and discusses technology readiness are also reviewed

Multiaperture Spectrometer

Proposed multiaperture spectrometer containing single grating provides high spectral resolution over broad spectrum. Produces parallel line images, each of which highly spectrally resolved display of intensity vs. wavelength in wavelength band of one of orders of spectrum produced by grating. Advantages; convenient two-dimensional spectral image, fewer components, and greater efficiency.
