Document Type and Number:
Japanese Patent JPH09503091
Kind Code:
A
Abstract:
An image intensifier tube that utilizes a photoresponsive layer for producing electrons in response to received radiation, a solid state electron amplifier for multiplying the electrons produced by the photoresponsive layer, a cold cathode for emitting electrons into vacuum, and a phosphor screen for converting impinging electrons into a visible image. The solid state electron amplifier is formed as a semiconductive layer interposed in between a photoresponse layer and a negative electron affinity layer on the photocathode. The solid state electron amplifier receives the electrons produced by the photoresponsive layer, multiplies the electrons and directs the electrons to the negative electron affinity layer. The negative electron affinity layer then directs the electrons through a vacuum to the phosphor screen producing a viewed image.
