Abstract(in English) | When laser light beams are allowed to propagate from one end of an optical fiber to the other end and further to be output onto a screen, irregular pattern called as speckle pattern can be observed in an output light spot. The authors previously reported the rotating phenomenon of speckle pattern when the optical fiber was placed onto a support plate in a loop-shape and the support plate was tilted. In this paper, an analysis procedure of a rotation angle of the speckle pattern in such rotation phenomenon has been studied through comparison between the results obtained from measurements utilizing an RIPOC method and the results obtained from manual measurements with an image processing software. As a result, the RIPOC method was confirmed to provide the rotation angle values close to the values obtained from the manual measurements. The obtained rotation angle values were confirmed be almost a half of the tilt angle of the support plate. |
