本文简要地介绍了利用８０３１单片机作为超短脉冲电火花光源控制部分的基本要求及其性能特点，给出了软硬件具体实现方法，对于实用性较强的定时和实时发光延时时间控制作了较为详细的分析。作为一种智能仪器，它实为纹影仪、阴影仪等其它光学仪器的理想配套产品，并可单独作为计时器或速度测量仪使用。 This paper briefly introduces the use of 8031 ​​single-chip ultra-short pulse spark control of the light source as part of the basic requirements and performance characteristics, gives the hardware and software to achieve the specific method for the practical and real-time timing of the luminous delay time control made A more detailed analysis. As a kind of intelligent instrument, it is actually an ideal matching product for other optics instruments, such as shadow masters and shades, and can be used as a standalone timer or speed measuring instrument.
