Abstract: Light whose wavelength is to be measured is applied to a device utilizing a light processing means which serves to transmit light to a detector array in a manner determined by its wavelength. The coded output of the detector array can thus immediately indicate the wavelength of the incoming light. I prefer to utilize a wedge interference filter to produce a line of light extending across the width of the filter at a position along its length, which position is a function of the wavelength. The position of the line of light is encoded by a binary code mask to digitally indicate the light wavelength. Indicator lamps are activated in accordance with the digital indication and are rendered responsive to the light from the code mask in response to a high sensitivity detector. The system broadly includes apparatus for measuring a light signal in which a plurality of signal transmission paths whose transfer functions are different functions of light wavelength effect transmission of the light signal to a unique combination of the output channels responsive to a specific input wavelength.
