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.

A photoelectric tube includes a housing including a light transmitting portion, an electron emitting portion including a photoelectric surface disposed inside the housing, an electron capturing portion disposed between the light transmitting portion and the photoelectric surface inside the housing, and a conductive layer disposed on a light transmitting portion side of at least a part of the electron capturing portion to face the photoelectric surface inside the housing and configured to allow light to pass therethrough.

Disclosed herein is a method comprising: emitting electrons from an electron ejector in response to an incident photon; driving the electrons through a hole toward a detector configured to collect the electrons and provide an output signal representative of the incident photon; driving the electrons away from sidewalls of the hole, using an electric field.
