| 1 | Long-Range Displacement Sensor Based on SMS Fiber Structure and OTDR显示文摘这份报纸由使用 single-multi-single 模式 SMS 纤维结构论述一个远程的排水量测量方法,属于在二永久的杆和光时间领域反射计之间的一个灵活盘子基于 OTDR 的讯问者。SMS 纤维结构传感器与二种不同配置被准备,即直并且正弦曲线配置。排水量传感器能与 0.159 公里的一个决定从 0 公里与一个范围执行排水量大小到 150 公里,这被表明。正弦曲线配置比直配置提供更好的敏感。建议传感器提议低费用,和它能为对民用的结构监视合适的伪分布式的排水量测量被实现。 | A.

| 2 | Graphene-and Multi-Walled Carbon Nanotubes-Coated Tapered Plastic Optical Fiber for Detection of Lard Adulteration in Olive Oil显示文摘A rapid and high-performance sensor for lard adulterant in edible oil was developed using the tapered plastic optical fiber(POF)coated with graphene and multi-walled carbon nanotubes.The coating material was deposited onto a tapered POF with a taper waist diameter and a taper length of 0.45 mm and 1 cm,respectively.The addition of the coating material was used to increase the sensitivity and selectivity coefficient of the tapered POF toward the lard substance.The sensing mechanism is based on a simultaneous interaction of lard substance and an evanescent wave of tapered POF with the coating layers.The results showed that graphene coating on the tapered POF increased the selectivity coefficient of the tapered POF towards lard substance from 33.54 to 324.19,and it gave a sensitivity of 0.427 dBm/%.In comparison,multi-walled carbon nanotubes coating increased the selectivity coefficient to 71.65 and increased its sensitivity to 1.189 dBm/%.Thus,the proposed configuration of the tapered POF with the coating material offered a simple configuration for a rapid,high sensitivity and selectivity detection of lard adulterant in edible oils. | Ika PUSPITA Ninik IRAWATI Kartika Anoraga MADURANI Fredy KURNIAWAN Sekartedjo KOENTJORO Agus Muhamad HATTA | 2022 | Photonic Sensors2022，12，4： | 2 |

| 4 | Heart Rate Monitoring Sensor Based on Singlemode-Multimode-Singlemode Fiber显示文摘The singlemode-multimode-singlemode(SMS)fiber structure for a heart rate monitoring is proposed and developed.An artificial electrocardiogram(ECG)signal is used to simulate the heart pulse at different rates ranging from 50 beats per minute(bpm)to 200 bpm.The SMS fiber structure is placed at the center of a loudspeaker and it senses the vibration of the pulse.The vibration of the pulse signal applied to the SMS fiber structure changes the intensity of the optical output power.The proposed sensor shows a linear frequency of the heart rate sensing range that matches well with the relevant heart rate from the artificial ECG.This work shows the capability of the SMS fiber structure monitoring the heart rate frequencies for a long term,high stability realization,and reproducibility,and being suitable for the observation in hospitals as well as in other environments. | Ninik IRAWATI Agus Muhamad HATTA Yoseph Gita Yhun YHUWANA SEKARTEDJO | 2020 | Photonic Sensors2020，10，2： | 0 |
