A non-contact displacement sensing system for a remote center compliance (RCC) device having a movable part and a fixed part, including: a curved reflector mounted for movement with one part of the RCC device; radiation source means, including at least one radiation source, mounted to the other part of the RCC device and spaced from the curved reflector for providing a beam of radiation to the reflector; and detector means including at least one detector device mounted to the other part of the RCC device and spaced from the curved reflector for receiving the reflected radiation from the radiation source means and generating outputs representative of the displacement of the suspended part relative to the fixed part.
