Resumo

This paper reports the development of a low-cost kit to turn smartphones into versatile platforms for interrogating optical fiber sensors. The adapter for connecting the fiber to the phone camera was 3D printed, whereas the application software was programmed for Android (TM) operating system. Different types of sensors based on multimode fiber and LED source were tested. The resolutions for the microbending displacement sensor, the fiber refiectometer, and the macrobending temperature probe are 26 mu m, 0.0006 RIU, and 3.9 degrees C, respectively. In addition to a didactic kit for photonics classes, the proposed device can also be used as a portable sensor for multiple purposes since the transducer modulus can be exchanged to assess different physical and chemical variables.
