The conception of new cryogenic-optical sensor for application in space, geodynamics and basic experiments is described. The sensor is based on magnetic suspension with a levitating probing body position and the signal processing system. The Michelson interferometer based on laser diode and single mode optical fiber was used as displacement sensor for probing body. Parasitic interference noises were appreciably suppressed by matching of laser diode radiation coherence length with difference of optical path in interferometer. The minimal detected displacement of the probing body was 0.1 nm. Design of sensor and mathematical model of dynamics of superconducting suspension were described. Results of experimental tests for magnetic suspension coupled with optical interferometric sensor of displacements with sub-nanometer sensitivity are presented.
