| description | The present invention is an apparatus for measuring the color of a light signal. The apparatus includes a plurality of color sensing elements, an optical system for illuminating each of the color sensing elements with light from the light source, and a controller for determining the intensity and wavelength of the light signal from the signals generated by said color sensing elements. Each color sensing element generates an electrical signal that depends on the wavelength and intensity of light incident on the color sensing element. Each of the color sensing elements is characterized by a gain function that relates the electrical signal generated thereby to the wavelength and intensity of light incident thereon. Each of the gain functions is different from the others of the gain functions. |
