Device for determining translational speed of body in relation to reference system based on Michelson interferometer, comprises bandpass filter, which filters measuring signal, which is adjusted on double frequency of rotation of turntable

摘要

The device comprises a bandpass filter, which filters the measuring signal, particularly an interference signal, which is adjusted on the double frequency of the rotation of the turntable. A light path is provided, which is guided by glass fiber. A winding (1,3) is provided, which is distributed in the level to each other, and generates multiple intersection points.
