Title
(EN) SENSOR ARRAY SPECTROMETER
(FR) SPECTROMÈTRE À RÉSEAU DE CAPTEURS
Abstract
(EN)
An optical device is disclosed and includes an optical sensor, a plurality of photosensitive pixels disposed on the optical sensor, a wavelength-selective optical filter in optical communication with the photosensitive pixels, and a plurality of spatially-variant written regions disposed in the optical filter, the written regions having a transmission spectrum and each of the written regions being larger than each of the pixels.
(FR)
L'invention concerne un dispositif optique, comprenant un capteur optique, une pluralité de pixels photosensibles disposés sur le capteur optique, un filtre optique sélectif en longueur d'onde en communication optique avec les pixels photosensibles, et une pluralité de régions écrites variant spatialement disposées dans le filtre optique, les régions écrites ayant un spectre de transmission et chacune des régions écrites étant plus grande que chacun des pixels.
