In this paper, we propose a new fiber bending sensor based on speckle
pattern imaging. The design and implementation of the sensor are demonstrated by
simulated studies. The speckle pattern imaging technique by using a multimode
fiber can offer high spatial resolution. In this study, we showed that the bending
sensor responds very sensitively by using the correlation of the images. The fiber
sensing part consists of a curve in a form similar to the S structure. We reached a
sensitivity of 0.0295 μm-1 by bending the fiber only 60°. Sensitivity can be further
increased by reducing the bending diameter or creating a full loop.
