Characteristics of Image intensifier. A) The intensifier can be turned on with a 0.1V change at the cathode. The threshold of fully opening is −1.3V. The gain becomes constant when the voltage < −1.3V until ~−20V as indicated by Lambert Inc. B-C) A sinusoidal modulation applied on the cathode turns on/off the intensifier producing a quasi square waveform. The offset around the −1.3V threshold controls the on/off time of the intensifier.
