概要
We have developed a newly sensing technique by which we can measure strain or temperature along an optical fiber with the high spa tial resolution of less than 1 mm. This fiber-optic distributed sensing technique is based on optical frequency domain reflectomet ry and it can map strain or temperature profiles along fiber Bragg grating. In this paper, the principle of this technique, distri buted strain sensing with the high spatial resolution and the applications to strain measurements of welded joints are described.
