An Investigation on a Photoelectricity Detection Terminal of a Liquid Level Sensor Using Hg Cladding Optical Waveguide

利用水银包层光波导 (HCOG)的衰减特性 ,制作光纤液位传感器 .与 80 98单片机相结合 ,实现信号探测及数据处理 .通过优化设计、器件选型 ,获得实时性很强的高精度测量 ,也可适用于其它光通信系统中微弱光信号的检测 .

We made the liquid level sensor by using the loss character of HCOG. With 8098 m icroporcessor, we implement the signal detection and data process. The good time tracing and high precision detection can be attained by optimized design and a pparatus selection. This detection terminal can be used in other optical communi cation system in detecting the weak optic signal.
