Abstract
The multiplex strain sensor with Optical Frequency Domain Reflectmetry (OFDR) is developed. By this system, simultaneous strain measurement of hundreds of points is theoretically possible. This measurement system has the potential to be used for health monitoring of aerospace structures and measurement of flexible structures dynamics. In this paper, the principle of this measurement system and the outline of the evaluation test results of this system are described.
