摘要

A concept of a cryogenic-optical sensor based on competitive adaptive sensitive elements applicable to a gravity meter sensor is considered. The sensor element is based on a magnetic levitation phenomenon, high-precision optical registration of levitating body mechanical coordinates, and robust signal processing tools. A controlled self-bearing probe dynamics is analyzed. An optimization approach to highly sensitive measurement of weak signal is presented. An optimization method which allows the extraction of the Lyapunov exponents from nonlinear chaotic dynamics of a macroscopic superconducting probe is described. Simulation results support the theoretical model, and the system characteristics are thus optimized.
