Title
(EN) MULTISPECTRAL SENSOR AND METHOD FOR MULTISPECTRAL LIGHT SENSING
(FR) CAPTEUR MULTISPECTRAL ET PROCÉDÉ DE DÉTECTION DE LUMIÈRE MULTISPECTRALE
Abstract
(EN)
A multispectral sensor comprises an opaque housing (OH) having a first chamber (CH1) with a first aperture (AP1) and a separate second chamber (CH2) with a second aperture (AP2). An optical emitter (OE) is arranged in the first chamber (CH1) and is arranged to emit light of a specified wavelength or range of wavelenghts through the first aperture (AP1). An optical sensor (OS) is arranged in the second chamber (CH2) and arranged to detect received photons through the second aperture (AP2). A control unit (CU) is configured to initiate emission of light by the optical emitter (OE) and a measurement unit (MU) is configured to provide sensor signals generated by the optical sensor (OS). The optical sensor (OS) comprises an array of sensor pixels of a first type (Spx) and pixels of a second type (Cpx). The pixels of the first type (Spx) each have a different transmission characteristic,each generating a multispectral sensor signal (MS), respectively. The pixels of the second type (Cpx) have a same transmission characteristic and each generate a compensation sensor signal (CS)..

La présente invention concerne un capteur multispectral qui comprend un boîtier opaque (OH) ayant une première chambre (CH1) avec une première ouverture (AP1) et une seconde chambre distincte (CH2) avec une seconde ouverture (AP2). Un émetteur optique (OE) est disposé dans la première chambre (CH1) et est conçu pour émettre de la lumière d'une longueur d'onde ou plage de longueurs d'onde spécifiée à travers la première ouverture (AP1). Un capteur optique (OS) est disposé dans la seconde chambre (CH2) et agencé pour détecter les photons reçus à travers la seconde ouverture (AP2). Une unité de commande (CU) est conçue pour initier une émission de lumière par l'émetteur optique (OE) et une unité de mesure (MU) est conçue pour fournir des signaux de capteur générés par le capteur optique (OS). Le capteur optique (OS) comprend un réseau de pixels de capteur d'un premier type (Spx) et de pixels d'un second type (Cpx). Les pixels du premier type (Spx) ont chacun une caractéristique de transmission différente, chacun générant un signal de capteur multispectral (MS), respectivement. Les pixels du second type (Cpx) ont la même caractéristique de transmission et génèrent chacun un signal de capteur de compensation (CS).
