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.
