Design of Current-Model Signal Source of Time Grating with Self-Compensation Technology

Abstract:

The measurement precision of time grating sensors is influenced by the phase symmetrical characteristic of three-phase exciting signal source. Therefore, a novel current-model exciting signal source with self-compensation technology is presented. In order to obtain high precision phase symmetry in stability, three orthogonal sine signals are generated by direct digital frequency synthesis (DDS) technology with self-checking and self-collection. Experiment results prove that the stability and measurement precision are improved significantly.
