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.

Abstract: 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.

Abstract: A power supply for an image intensifier of a night vision device is disclosed. The power supply comprises a battery, a memory, and a processor. The processor is configured to turn off a switch via which a voltage is supplied to a photocathode of the image intensifier in response to current drawn by an anode of the image intensifier. The processor is further configured to store, as a stored voltage value, a value of the voltage in the memory. The processor is further configured to turn on the switch and re-apply a voltage to the photocathode in accordance with the stored voltage value after a first predetermined period of time. The processor is further configured to enable an automatic brightness control procedure using the stored voltage value.
