摘要
利用气体分子的吸收光谱,采用分布反馈式半导体激光器(DFB LD)作为光源,使用拓普公司数据采集卡PCI-10016,研究了一种基于计算机的光纤气体传感器谐波检测的实验室解调方案,设计了解调软件进行信号解调,实现了气体体积分数的谐波检测,并能实时显示采集波形及分析波形,检测分辨力可达30×10-6,有很大的实用价值.
A kind of vibration acceleration-frequency detecting device is described,which is a new style low power consumption handy device based on ADXL50 acceleration sensor.The detecting device can be used for inspecting the vibration parameter of missile launch vehicle in real time when it is in the process of marching and erecting.It solves the problem that the traditional vibration accelerationfrequency-detecting device that can only be fixed on one place is very difficult to assure the stability of swing and the stability of frequency.
