本文将介绍一种新设计的光学示波器的核心部件——通用超快速变象管。这种管型的光电阴极设计成带状线结构,它将和外回路的同轴线匹配连接,使半宽度可短至几十皮秒的快门电压脉冲方便地加到光电阴极上,从而可实现超短的分幅曝光时间。本管型所采用的电子光学系统对快门电压脉冲波形没有严格的要求,即使其波形为前后沿较长 This article will introduce a new design of the optical oscilloscope core components - Universal ultra-fast image tube. The tube-type photocathode is designed as a stripline structure that is mated with the coaxial line of the outer loop so that a shutter voltage pulse half-width can be as short as a few tens of picoseconds can be conveniently applied to the photocathode so that To achieve ultra-short shot exposure time. The tube used in electronic optical shutter voltage pulse waveform is not stringent requirements, even if the waveform for the front and back along the longer
