  • Device for and method of measuring absolute rotations in several directions in space
    Patent number: 5818589
    Abstract: To measure absolute rotations in several directions in space with the aid of interferometers, one interferometer is required for each direction in space. According to the invention, it is proposed to supply a device consisting of several interferometers from a common light source and to switch only the phase modulation impressed on the light rather than the light paths, using time-division multiplexing. The output signals from the interferometers are detected and evaluated with a single detector and evaluating unit.
