Abstract
An example system includes a housing defining a cavity and an aperture, a photodetector disposed within the cavity, a voltage-tunable interferometer disposed within the cavity between the aperture and the photodetector, a first light source disposed within the cavity, and an electronic control device. The electronic control device is operable to vary an input voltage applied to the interferometer, and concurrently, cause the first light source to emit light towards the interferometer and measure light reflected from the interferometer using the photodetector. The electronic control device is also operable to determine a calibrated input voltage based on light reflected from the interferometer and measured by the photodetector. The electronic control device is also operable to apply the calibrated input voltage to the interferometer, and concurrently, obtain one or more spectral measurements using the photodetector.
