电流调制垂直腔面发射半导体激光器混沌动力学特性-Current modulation vertical cavity surface emitting semiconductor lasers dynamic characteristics of chaos

使用体型较小的STC12C2052实现超声波测距的功能，设计实验板为5cm*7cm的洞洞板。(The function of ultrasonic distance measurement is realized by using the smaller STC12C2052, and the cavity plate of the experimental board is 5cm*7cm.)
