Abstract:
A system for detecting radiation, the system comprising:a. two or more sensors operable to sense input radiation having a unique wavelength and to generate two or more sets of sensor data, each sensor comprising a detector and a filter, each filter associated with at most one detector; b. each sensor operable to sense radiation within a substantially similar wavelength range, each sensor having a different responsivity curve, a function of the responsivity curves yielding a combined function of the sets of sensor data; c. a processing module operable to receive the sets of sensor data and to determine the unique wavelength for the input radiation that is sensed by the sensors from the sets of sensor data according to the combined function, the unique wavelength determined by inputting the sets of sensor data into the combined function to yield an output corresponding to the unique wavelength; and d. a display operable to display the unique wavelength.
