摘要：
The plastic optical fiber (POF) with a multi-notched structure was used for liquid level measurement. The multi-notched structure was fabricated on the POFs by a die-press-print method. When the notched structure was immerged by the liquid, the transmitted light power of the POF probe could be changed. So, this can be used as a liquid level sensor. The influence of the structure parameters on the sensor performances was investigated experimentally. Experimental results show that the sensitivity can reach to 0.0457/mm with a resolution of 1 mm, and the sensor resolution is flexible. The sensor is simple structure and easy fabrication, and it is a low cost solution for the liquid level measurement.
