摘要：Methods and systems are provided for calibrating seismic sensors configured ordesigned for use in seismic signal detection. According to certain embodiments of thepresent disclosure, a current is injected into a moving coil of a seismic sensor and avoltage is measured across the moving coil. The moving coil is locked by the injectedcurrent such that environmental noise is reduced while measuring the moving coilvoltage.
