Title (EN) DIFFRACTIVE FOCUSING LENS FOR INFRARED DETECTOR
(FR) LENTILLE DE FOCALISATION A ELEMENTS DE DIFFRACTION POUR CAPTEUR INFRAROUGE
Abstract: front page image
(EN)A focussing element (50) is incorporated in an infrared detector, the focussing element (50) being in the form of a series of grooves (54) which form one or more diffractive optical elements. The diffractive optical elements may have spatial filtering properties and may also be arranged to correct chromatic aberrations. Alternatively, the focussing element may comprise a holographic optical element.
(FR)L'invention concerne un élément de focalisation (50) incorporé dans un capteur infrarouge, cet élément (50) se présentant sous la forme d'une série de rainures (54) qui forment un ou plusieurs éléments de diffraction optique. Ces éléments peuvent posséder des propriétés de filtrage spatial optique, et être agencés de façon à corriger des aberrations chromatiques. Selon un autre mode de réalisation, l'élément de focalisation comprend un élément optique olographe.
