Body translation speed determining device for use in e.g. terrestrial surrounding, has evaluation electronics and measuring system for determining light speed variations between different spatial directions

摘要

The device has evaluation electronics and a measuring system for determining light speed variations between different spatial directions, where an interferometer including a light source (13) with less coherence length and a phase measuring device serves as the measuring system. The system is position-changeable with respect to a body based on application purpose and is connected with the body in a rigid manner.
