ABSTRACT:
A time dispersed sensor tube has a photocathode for receiving light images and converting them to photoelectrons. An anode adjacent the photocathode has a slit-diaphragm for accelerating photoelectrons and passing them to slit-jaws by way of a shutter electrode and counterelectrode. A deflection system is provided behind the slit-jaws for directing the photoelectrons to a screen. A short magnetic electron lens between the deflection system and the screen focuses the photoelectrons.
