Abstract

The operation principle of a new type of intensity modulate macrobend curvature optical fiber senor was presented based on surface light scattering theory. Sensor's static and dynamic performance was investigated. This type of sensor can distinguish between positive and negative bending directions. When curvature radius is larger than 50 mm, the sensor will keep good linearity. Two-dimensional shape measurement experiments using curvature sensors have been implemented.
