A simple mirrorless plastic optical fiber displacement sensor was used to determine the concentration of paracetamol (PCM) in an aqueous solution. Paracetamol concentrations between 5 and 45 ppm were tested by the proposed sensor. With a mirror, the substantial sensitivity observed by an output power changed against displacement of 0.0403 mW/μm for the front slope and 0.023 mW/μm for the back slope with linearities of more than 99%. On the other hand, nonmirror reflector showed a sensitivity of 0.0006 mW/μm for the front slope and 0.0002 mW/μm for the back slope for the case of a red reflector and a sensitivity of 0.0007 mW/μm and 0.0003 mW/μm for the front and the back slope, respectively, for the case of a white reflector. The sensor sensitivity for the red and white coloured papers, which were used as the nonmirror reflectors and the mirror reflector itself against changing PCM concentrations, was 0.0004 mW/ppm, 0.0008 mW/ppm, and 0.02 mW/ppm, respectively. The experimental results indicated that the sensor was not only able to detect and measure the concentration of PCM in aqueous solutions but was also very stable with the additional advantages of a cost-effective and practical design that is highly beneficial for real-world sensing applications.

阐明用于检测扑热息痛的无镜大芯捆绑塑料光纤位移传感器的能力

使用简单的无镜塑料光纤位移传感器来确定水溶液中扑热息痛 (PCM) 的浓度。所提出的传感器测试了浓度在 5 到 45 ppm 之间的扑热息痛。使用镜子，输出功率观察到的显着灵敏度随前斜率0.0403 mW/ μm和背斜率0.023 mW/ μm 的位移而变化，线性度超过 99%。在另一方面，nonmirror反射显示的0.0006毫瓦/灵敏度μ米用于前斜率和0.0002毫瓦/ μ m表示用于红反射器的情况下，和0.0007毫瓦/的灵敏度背面斜率μ m和0.0003毫瓦/ μ对于白色反射器的情况，m 分别为前斜率和后斜率。用作非镜面反射器和镜面反射器本身对 PCM 浓度变化的红色和白色纸的传感器灵敏度分别为 0.0004 mW/ppm、0.0008 mW/ppm 和 0.02 mW/ppm。实验结果表明，该传感器不仅能够检测和测量水溶液中 PCM 的浓度，而且非常稳定，具有成本效益和实用设计的额外优势，对现实世界的传感应用非常有益。
