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.

Usage and temperature compensation of performance parameters for night vision device

A method of controlling the performance of a night vision device includes storing, in memory of the night vision device, a plurality of performance configuration parameters, and after the storing, applying at least one of a hardware lock and a software lock to the night vision device such that at least some of the plurality of performance configuration parameters stored in the memory cannot be changed.

Programmable performance configurations for night vision device

A methodology, for night vision equipment, includes enabling an automatic brightness control (ABC) procedure for a light intensifier having a photocathode that automatically selects a voltage to be applied to the photocathode, sensing current being drawn by the anode, when the current being drawn by the anode exceeds a predetermined threshold, shutting down the photocathode, disabling the ABC procedure, and storing, as a stored voltage value, a value of a voltage that had been selected by the ABC procedure when the current exceeded the predetermined threshold. After a first predetermined period of time, applying a voltage to the photocathode in accordance with the stored voltage value, and after a second predetermined period of time re-enabling the ABC procedure and selecting the stored voltage value as the voltage to be applied to the photocathode.
