ABSTRACT:
A miniature flat panel image intensifier tube display device using two inne microchannel plate (MCP) electron multipliers that have two arrays of orthogonally positioned electrically isolated parallel metallic stripes as electrodes on their interfacing surfaces and have the conventional continuous electrodes on the other two surfaces. A solid photocathode layer is in proximity focus with the solid input electrode of the first MCP, and the solid output electrode of the second MCP is in proximity focus with a display device. Array switching electronic means selectively switches bias voltages in some selected scan mode over the two arrays of MCP metallic stripes to provide a selective electron charge pattern exiting the second MCP wherein the charge pattern is converted to a visible image at the display device.
