Abstract
A device for measuring an extremely diminished intensity of light by superposing a plurality of streaking images of the light beams caused by fluorescence occurring in a phosphor layer where secondary electrons are incident thereon in single photon units. A streaking image is formed by secondary electrons generated within a streaking tube through which electrons generated in a photoelectric layer therein are accelerated to the phosphor layer therein when passing through a micro-channel-plate therein. The superposed streaking images with enhanced brightness are then picked up by a television camera.
