State Of The Art Of Image Intensifiers

In this paper a variety of currently fabricated image intensifiers are discussed. The operation of these tubes is explained and their main characteristics distinguishing them from other types are described. The most important characteristics for the performance are noise characteristics expressed by the signal to noise ratio at the output S/No and imaging characteristics expressed by the Modulation Transfer Function (MTF). Current efforts concentrate on improving these two parameters and on lowering fabrication costs.
