The idea of stabilized wavelength within a certain defined measuring range leads quite directly to a cavity - based design. A passive Fabry-Perot cavity has been traditionally used as an etalon for laser frequency stabilization in a large number of configurations and applications. Linking a laser optical frequency to a resonance of the cavity means in fact a stabilization of wavelength within a cavity where the standing wave has been generated. We tried to use this grid of the standing wave as a reference for direct position sensing. The concept of measuring within a standing wave generated by a reflector has been reported previously, but we propose here the measurement within a cavity together with the effect of stabilization of wavelength.
