提出了一种基于D型腐蚀石英光纤的液位传感器。传感器的光传输取决于液位。该传感器可以实现为具有高分辨率的连续液位传感器，并且仅需要一根光纤和一个光源和检测器。我们已经证明了一个传感器的分辨率类似于1毫米。该传感器适用于液体的折射率大于类似于1.45。我们表明，传感器的响应是相同的增加和减少的液体水平。(c)2007年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。
A liquid level sensor based on etched D-shaped silica optical fibers is presented. The optical transmission of the sensor depends on the liquid level. The sensor can be realized as a continuous level sensor with a high resolution and requires only one fiber and one optical source and detector. We have demonstrated a sensor with a resolution of similar to 1 mm. The sensor works for liquids with refractive indices greater than similar to 1.45. We show that the sensor response is the same for increasing and decreasing liquid levels. (c) 2007 Society of Photo-Optical Instrumentation Engineers.
