Abstract

An integral sensing head includes a single fiber optic faceplate substrate to which are connected photodiode arrays, circuits for selectively controlling the transmission of electronic information signals from the photodiodes and interconnecting conductive lines all disposed on the same fiber optic faceplate substrate which thereby provides the optical lens system for the photodiodes and a supporting substrate to which the active components are mounted and electrically interconnected by conductive lines.
