专利汇可以提供Fast response automatic brightness control circuit for second generation image intensifier tube专利检索,专利查询,专利分析的服务。并且A fast response automatic bright source protection circuit for an image intensifier tube in which the amount of screen current, which is produced according to the light intensity of a target source, is sensed at the gate electrode of a junction FET. The gate electrode of the junction FET is connected between a resistor and a low junction capacitance diode that are serially connected in the path of the screen current. Since the diode has a very low junction capacitance, any fluctuation in the screen current has a very short transient time at the gate electrode of the junction FET. The drain electrode of the FET controls the drive of voltage regulated oscillators. The voltage regulated oscillator outputs are transformer coupled to voltage multipliers whose outputs produce large direct current bias voltages that are applied to the cathode, to the input and the output electrodes of a microchannel plate, and to the screen. These bias voltages applied to the input and output electrodes change inversely with any change of the screen current. Therefore, with the microchannel plate bias voltages varying inversely with the screen current, the brightness of the target source being viewed through the image intensifier remains constant at the output of the image intensifier tube.,下面是Fast response automatic brightness control circuit for second generation image intensifier tube专利的具体信息内容。
