Photocathode gating offers the benefits of extending the dynamic range of an image intensifier (I2) tube as well as enabling a digital operating mode for camera and LIDAR applications, and has had applicability in the military, scientific, and industrial fields. Conventional gating applications have been limited to system level solutions, wherein the temporal characteristics of the photocathode gating signal are controlled at the system level. In these systems, the I2 and associated power supply act as slaves to the gating control inputs from system control electronics. Recently, Northrop Grumman Electro-Optical Systems (NGEOS) has applied the concepts of photocathode gating to the development of high performance miniature wrap-around power supplies used on 18mm and 25mm Generation III I2 filmed and Unfilmed MCP based tubes for military applications. Offering internal stand-alone sensing and control of gating characteristics for the I2 (Autogating), these devices provide the user with the advantages of increased dynamic range in a drop-in replacement solution into existing night vision systems.
