Abstract
An array of detectors of electromagnetic radiation is positioned behind a pair of “grade” or “variable” filters and are inclined with respect to each other so that the detectors view a range of center wavelengths of varying bandwidths.
Claims13
A radiation sensor comprising an array of detectors of electromagnetic radiation, and first and second filters positioned in front of the array whereby to limit the wavelength response of the detectors, each filter having a transmission characteristic which varies along a physical dimension, said filters being positioned such that their said dimensions are inclined with respect to each other.
