Abstract
(EN)
An example system includes a first light source, a second light source, a photodetector, and an electronic control device. The electronic control device is operable to cause the first light source to emit first light within a range of wavelengths towards a subject, and measure, using the photodetector, the first light reflected from the subject. The electronic control device is also operable to cause the second light source to emit second light including a plurality of emission peaks within the range of wavelengths, and measure, using the photodetector, the second light. The electronic control device is also operable to determine spectral information regarding the subject based on the measured first light and the measured second light.

Un système donné à titre d'exemple comprend une première source de lumière, une seconde source de lumière, un photodétecteur et un dispositif de commande électronique. Le dispositif de commande électronique peut fonctionner de sorte à amener la première source de lumière à émettre une première lumière dans une plage de longueurs d'onde vers un sujet, et à mesurer, à l'aide du photodétecteur, la première lumière réfléchie par le sujet. Le dispositif de commande électronique peut également fonctionner de sorte à amener la seconde source de lumière à émettre une seconde lumière comprenant une pluralité de pics d'émission dans la plage de longueurs d'onde, et à mesurer, à l'aide du photodétecteur, la seconde lumière. Le dispositif de commande électronique peut également fonctionner de sorte à déterminer des informations spectrales concernant le sujet sur la base de la première lumière mesurée et de la seconde lumière mesurée.
