Zusammenfassung: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.
