When coherent light beams (laser beams) are incident on one end of an optical fiber, transmitted to another end thereof to exit from there so as to form an output light spot on a screen, non-uniform intensity distribution called a speckle pattern is often recognized in the output light spot. The authors are trying to utilize changes in such speckle pattern caused by certain external disturbances applied to the optical fiber for the purpose of sensing of the applied external disturbances. In this paper, a multimode optical fiber was placed in a loop onto a support plate and the speckle pattern in the output light spot was observed while rotating the support plate. As a result, the speckle pattern appeared to be rotating in accordance with rotation of the support plate. Quantitative measurements indicated that the pattern rotated approximately in proportion to the support plate rotation. |
