1. A night vision system, comprising:
an analog image intensifier tube;
an addressable display within the analog image intensifier tube configured to create an electronically addressable output;
a digital imager configured to receive an optical image and produce a plurality of digital electrical signals corresponding to the optical image; and
a controller configured to produce a symbol digital electrical input onto the plurality of digital electrical signals;
wherein the analog image intensifier tube is configured to receive the optical image and to produce multiplied electrons from the addressable display comprising an electron multiplier within the analog image intensifier tube, and to also produce electrons from electron emitters on the electron multiplier that are addressed on a pixel-by-pixel basis by the plurality of digital electrical signals.
