ROTATION SPEED MEASURING APPARATUS |
摘要 |
A closed light path is traversed by two light beams passed in opposite direction. The beams are then superimposed and their phase shift evaluated. The light path is provided by a light conductor embedded in a setting material which damps out external sound waves. A highly uniform temp. distribution is set up along the light conductor owing to the nature of the setting material. |
