Paper Abstract

Compact spectrometers are of interest for space applications for both Earth observation and analysis of planet soil. The spectrometer here described is dedicated to Land imaging and is based on the use of linear variable filters for wavelength selection. This kind of filter is able to transmit the radiation in a narrow band (<20 nm) centered on a wavelength that changes along its surface, and to operate in a wide spectrum (visible-infrared). Both the variable filter characteristics and the results of the breadboard spectrometer operation will be reported.
