Usage and temperature compensation of performance parameters for night vision device

A power supply for a light intensifier of a night vision device, the power supply comprising:

• power supply circuitry that is configured to supply a control voltage to the light intensifier;
• a chronometer;
• a temperature sensor;
• a memory configured to store control logic;
• and
• a processor that is in communication with the chronometer, the temperature sensor and the memory, wherein the processor is configured to execute the control logic to:
• supply, by the power supply circuitry, to a microchannel plate of the light intensifier, a control voltage that controls a gain of the microchannel plate;
• determine, based on a value of the chronometer, whether the night vision device has been used for a predetermined amount of time;
• when the night division device has been used for the predetermined amount of time, determine 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 based on a value of the temperature sensor;
• adjust the control voltage in accordance with the amount of compensation to obtain a compensated control voltage;
• and
• supply, by the power supply circuitry, the compensated control voltage to the microchannel plate of the light intensifier,
• wherein the compensated control voltage is calculated according to the following equation:
• V(t)=V(tprevious)+Δt*ΔV*δ(T),
• wherein V(t) is the compensated control voltage at a given time t, ΔV is a correction added to a set point of the control voltage, δ(T) is a correction due to temperature, Δt is an amount of time the night vision device has been subject to a high light condition.
