High-Speed Image Monitoring of Baseplate Movement in A Vibrator

摘要

Systems, sensors, and methods for high-speed image monitoring of baseplate movement in a vibrator. The systems can include a baseplate defined by an area, disposable at a ground surface to direct a seismic force into the ground surface. The system can include a reaction mass coupled to and positioned above the baseplate to generate the seismic force at the baseplate. The system can include an actuator assembly coupled to the reaction mass to vibrate the reaction mass, as well as high-speed image units directed at the area of the baseplate. The high-speed image units can include photo detectors to sense a distribution of acceleration across the area of the baseplate, and a light source emit light to be sensed by the photo detectors. The system can also include a controller coupled to the actuator assembly, that drives the actuator assembly.

1. A system for high-speed image monitoring of baseplate movement in a vibrator, comprising:
a baseplate defined by an area, disposable at a ground surface configured to direct a seismic force into the ground surface; a reaction mass coupled to and positioned above the baseplate configured to generate the seismic force at the baseplate; an actuator assembly coupled to the reaction mass configured to vibrate the reaction mass; one or more high-speed image units directed at the area of the baseplate, comprising:
a plurality of photo detectors configured to sense a distribution of acceleration across the area of the baseplate; anda light source configured to emit light to be sensed by the plurality of photo detectors; and a controller coupled to the actuator assembly, the controller configured to drive the actuator assembly.
