Abstract
The present invention relates to a spectral detection device (100) for detecting spectral components of received light, wherein the spectral detection device (100) comprises a filtering structure (110) arranged to filter the received light and output light with a wavelength within a predetermined wavelength range; and a light sensor (120) arranged to detect the light output by the filtering structure (110), wherein the filtering structure (110) is variable to allow a variation of the predetermined wavelength range over time.
