Title (EN) ACTIVE SHORT-WAVE INFRARED FOUR-DIMENSIONAL CAMERA
(FR) CAMÉRA QUADRIDIMENSIONNELLE À INFRAROUGES DE COURTE LONGUEUR D’ONDE ACTIVE
Abstract:
(EN) A lidar system operates as an active short-wave infrared (SWIR) camera system to determine a four-dimensional image at each point in a two-dimensional field of regard. The camera system includes a short-wave infrared spectrum scanner that transmits a pulse of light at a particular position or coordinate in a two-dimensional field of regard and a receiver that detects return pulses scattered from a target in the field of regard coincident with the particular position. The receiver includes a detector that detects the returned pulse, a range determination unit that determines, based on the timing of the returned pulse, a distance to the target at the particular position, and an intensity measurement unit that determines the magnitude, amplitude, or intensity of the returned pulse, which information provides an indication of the relative, or in some cases, absolute reflectivity of the target at the particular point in the field of regard.
(FR) L’invention concerne un système de lidar qui fonctionne en tant que système de caméra à infrarouges de courte longueur d’onde (IRCL) pour déterminer une image quadridimensionnelle au niveau de chaque point dans un champ d’observation bidimensionnel. Le système de caméra inclut un numériseur de spectre infrarouge de courte longueur d’onde qui émet une impulsion de lumière à une position ou une coordonnée particulière dans un champ d’observation bidimensionnel et un récepteur qui détecte des impulsions de retour dispersées d’une cible dans le champ d’observation coïncidente à la position particulière. Le récepteur inclut un détecteur qui détecte l’impulsion de retour, une unité de détermination de portée qui détermine, sur la base de la temporisation de l’impulsion de retour, une distance à la cible à la position particulière, et une unité de mesure d’intensité qui détermine la magnitude, l’amplitude, ou l’intensité de l’impulsion de retour, lesdites informations contenant une indication de la réflectivité relative ou, dans certains cas, absolue, de la cible au point particulier dans le champ d’observation.
