本文叙述了光笔的一般知识,在初步试验基础上,提出以光笔跟踪方式录取显示器上目标座标数据。试验在常用的31SS 32D 示波管上进行,产生32个光点组成的十字光标只用了40μs,跟踪速率可达300～400mm/s。文中认为在半自动录取座标及干予计算机实施指挥控制时,采用光笔有较大优越性。
This paper describes the general knowledge of the light pen, and proposes to record the target coordinate data on the display with the light pen tracking method on the basis of the preliminary experiment. The experiment was carried out on a commonly used 31SS 32D oscilloscope. The cross cursor with 32 spots produced only 40μs and the tracking rate was 300-400mm / s. In the paper, it is considered that the use of light pen has great advantages in semi-automatic admission of coordinates and implementation of command and control to computers.
