【摘要】 本文提出了一种新型的光纤液位传感器，它的感受部分用热刻—酸蚀法直接配置在光纤上，使得感受应变量的结构成为光纤本身的固有结构。这种传感器具有线性的液位响应及较好的重复性且没有滞后效应，与其它传感器相比其最大的优点是高灵敏度，可望用于液位高Ｈ＞１０ｃｍ时的精细测量。更多还原

【Abstract】 Presented in this work is a novel optical fiber liquid position sensor. It uses the method that combines the thermal carving technique with chemical etching. The response of the sensor under liquid position change is linear、repeatable and no measurable hysteresis. The sensor, which is superior to other liquid position sensors, has higher sensitivity when the height of liquid is higher than 10cm.更多还原
