Abstract
Design of multiple-bend extensometer based on optical fiber as landslide sensor has been characterized. Multiple-bending characterization has been done by varying the winding number of optical fiber FD-620-10 to obtain the effective light intensity of photodiode. The light intensity in extensometer was set by varying the resistance of laser diode in the range (150 – 250) Ω. The optimum sensitivity of 0,03984 V/cm was obtained for triple winding of optical fiber. The designed optical extensometer is able to monitor the displacement with an error of 0,59%. This result indicates that the designed extensometer is the more bending on optical fiber, the more it’s sensitivity and the bending loss.
