  • Patent number: 11901168
    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.

  • Patent number: 9230783
    Abstract: A power supply for an image intensifier, the power supply including a DC voltage source generating a photocathode voltage; a bright source protection (BSP) resistor in series with the DC voltage source; and an oscillator in parallel with the DC voltage source and the BSP resistor, the oscillator providing an AC voltage component, the AC voltage component having a fixed pulse width, the AC voltage component being coupled to the photocathode by a diode, the pulse width and shape of the AC voltage component on the photocathode being determined by the photocathode current.
