Abstract This manuscript describes a novel standingwave arrangement with two laser sources of different wavelengths, emitting towards each other. The resulting standing wave has a continuously moving intensity profile, a thin, transparent photo sensor is inserted into. When the sensor is moved along the optical axis a frequency shift, proportional to the velocity, occurs. This frequency shift can be evaluated for the purpose of interferometric length measurements.
