1.In this paper,GaAlAs DPL is used for measuring the height of clouds and a new method of counting pulses_collecting and counting the pulses during the course of transmitting and detecting,which is different from the conventional pulsecounting.
利用脉冲 Ga Al As二极管激光器进行了云高测量 ,提出了一种区别于传统的脉冲计数方法—单脉冲全程计数法收藏指正
2.Researching the domestic and external development status of robot, we forward a hardware structure basing on DSP and Complex Programmable Logic Device (CPLD). CPLD is used to accomplish the direction decoding, four frequency multiplication and counting for two quadrature encoder pulse.
