| 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, we examined the method for estimating tilted angles to classify speckle pattern images by ResNet-18 trained using transfer learning. As a result, the network with a classification accuracy of approximately 95% in the measurement range of -10 to +10 degrees of tilt angle was realized. |
