Sagnac effect

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

A phenomenon encountered in interferometry that is elicited by rotation. The Sagnac effect manifests itself in a setup called a ring interferometer. A beam of light is split and the two beams are made to follow the same path but in opposite directions. To act as a ring the trajectory must enclose an area. On return to the point of entry the two light beams are allowed to exit the ring and undergo interference. The relative phases of the two exiting beams, and thus the position of the interference fringes, are shifted according to the angular velocity of the apparatus.

日本語の意味

光干渉計において、環状に配置された経路を利用して、回転運動により発生する光の位相差を示す現象。具体的には、光のビームを分割し、互いに反対方向へ進ませることで得られる干渉パターンが、装置の角速度に応じてずれる現象を指す。
