ABSTRACT:
An optical sensor has an electrically adjusted mosaic filter in which each optical filter element of the mosaic filter covers a photosensitive device or region disposed adjacent to the filter. The electrical signals from each photosensitive region or device is amplified, varied and summed to produce an optical sensor output substantially matching a desired spectral response curve as a function of varying the amplified outputs of the photosensitive regions.
