Abstract
An electromagnetic radiation measurement device is disclosed, including an electromagnetic radiation sensor and a reconfigurable filter assembly. The reconfigurable filter assembly has a series of configurations, each configuration of the series filtering to a different wavelength band for measuring by the sensor. The wavelength bands of adjacent configurations of the series overlap thereby to define differential sub-bands. The device also includes a processor configured to utilise sensor measurements for different configurations of the series to derive measurement values for the sub-bands.
