Research Abstract

This research proposed the new measurement method which can measure directly the linear speed using a slow light and an optical gyroscope. The experimental device for evaluating the principle of the measurement method was set, and the speed measurement experiments were conducted. As a result, correlation was found between the frequency of detected light and speed, and the possibility of the proposed measurement method was shown. However, the same result was obtained in the speed measurement experiments without using a slow light. Therefore, it is thought that the speed was detected by the principle different from the proposed principle. This research showed that it is important to clarify the detection principle of the speed in these experiments.
