一九八○年十一月在波士顿电光/激光会议上,美国国际电话电报公司的H·J·BuRBo详述了脉冲发光器和夜视系统图象器距离选通间的设计方法,给出了探测器和激光器距离选通目前可行性组合的通俗易懂的一览表。BuRBO主张光阴极仍然胜过较新的探测器。就功率输出讲,要注重考虑对眼睛安全的效应。尽管采用一个或两个图象增强管,电视系统的脉冲重复频率可以不受限制,但BuRBO认为在水平回扫时间内,精确同步地发射发光器,可使电子干扰减低到最低限度。他说,作用距离通常不限制脉冲重复频率。 移象管选通要考虑负载和电压摆动,但是由于采用第二代图象增强管不会受到过大的限制。然而,在电子变象管中,图象尺寸随着选通电压上升迅速地改变,因而引起某些聚焦问题。
HJ BuRob, AT & T, at the Ottawa / Laser Conference in Boston, 1980, gave a detailed account of the design of the distance gating between the pulse emitter and the night-vision system imager, giving An easy-to-understand list of detector and laser distance gating current feasibility combinations. BuRBO claims that the photocathode still outperforms newer detectors. Speaking of power output, pay attention to consider the effect of eye safety. Despite the use of one or two image enhancement tubes, the pulse repetition frequency of the television system can be unrestricted, but BuRBO believes that transmitting the emitters accurately and synchronously during a horizontal flyback period minimizes electronic interference. He said that the range of action usually does not limit the pulse repetition frequency. The shift tube gate should take into account the load and voltage swing, but due to the use of second-generation image enhancement tube will not be subject to excessive restrictions. However, in electronic picture tubes, the size of the picture changes rapidly as the gate voltage rises, causing some focus problems.
