Abstract

L'invention concerne un dispositif optique comprenant un corps qui héberge un détecteur, un réseau de diffraction et une lentille permettant de focaliser la lumière réfléchie par le réseau de diffraction sur le détecteur. Ledit corps est équipé d'une fenêtre laissant passer la lumière de l'extérieur du dispositif optique vers réseau de diffraction. Dans un mode de réalisation préféré, le réseau de diffraction présente un pas variable permettant d'obtenir une imagerie linéaire. La lentille présente une faible ouverture numérique, et le détecteur est aligné selon un angle non perpendiculaire à l'axe optique de la lentille d'imagerie.
