Abstract: A night vision system along with an image intensifier tube and method for forming the tube are provided. The night vision system incorporates the image intensifier tube in both an analog channel as well as a digital channel, with an addressable display within the analog image intensifier tube analog channel configured to create an electronically addressable output. An analog image intensifier tube is included in the digital imager for presenting binary digital signals representative of an image, or of symbol indicia, and registering those digital representation from the digital imager onto one or more electron multipliers of the analog image intensifier tube within the analog channel. The provided night vision system also utilizes a cathodoluminescent screen, which is a highly efficient light source that reduces system power.

Abstract: A night vision system along with an image intensifier tube and method for shuttering the continued draw of electrons from an electron multiplier are provided. The night vision system includes the electron multiplier, or possibly two electron multipliers, each comprising a silicon membrane. A shutter voltage is applied between a first surface and a substantially parallel, opposed second surface of the silicon membrane to discontinue draw of electrons through the electron multiplier and for substantially discontinuing display of an image from the image intensifier tube under certain bright light conditions. Utilizing a global shutter control on the electron multiplier, and the significantly lower voltage for such control mitigates power consumption within the image intensifier, as well as electromagnetic interference and delay response time. A relatively low voltage negative bias shutter voltage on only the electron multiplier selectively provides global shutter to the image intensifier device.
