Abstract: An apparatus, system and method is provided for producing stacked wafers containing an array of image intensifiers that can be evacuated on a wafer scale. The wafer scale fabrication techniques, including bonding, evacuation, and compression sealing concurrently forms a plurality of EBCMOS imager anodes with design elements that enable high voltage operation with optional enhancement of additional gain via TMSE amplification. The TMSE amplification is preferably one or more multiplication semiconductor wafers of an array of EBD die placed between a photocathode within a photocathode wafer and an imager anode that is preferably an EBCMOS imager anode bonded to or integrated within an interconnect die within an interconnect wafer.

Abstract: A method of controlling the performance of a night vision device includes supplying, by a power supply, to a microchannel plate of a light intensifier tube, a control voltage that controls a gain of the microchannel plate, determining an amount of compensation to apply to the control voltage based on a change to the control voltage attributed to a change in temperature of an operating environment of the night vision device, adjusting the control voltage in accordance with the amount of compensation to obtain a compensated control voltage, and supplying, by the power supply, the compensated control voltage to the microchannel plate of the light intensifier tube. The method may further include determining whether the night vision device has been used for a predetermined amount of time, and only after that predetermined amount of time, is the method configured to supply the compensated control voltage.
