Abstract: 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.

Abstract: Cleaning mechanisms for optical elements are disclosed herein. Example apparatus disclosed herein to clean an optical element can include a cover positionable over a first side of the optical element. In some examples, the cover is controllable to transition between a first position and a second position. For example, the cover can form a gap between a first side of the optical element and the cover when the cover is in the first position, and the cover can provide the optical element with access to a field-of-view when the cover is in the second position. Such example apparatus can also include a flushing assembly controllable to inject cleaning fluid into the gap when the cover is in the first position. In some examples, the flushing assembly also includes a valve that is controllable to permit the cleaning fluid to exit the gap after having been injected into the gap.

Abstract: Downhole imaging systems and methods are disclosed herein. An example method includes projecting flushing fluid into an optical field of view of an imaging system disposed on a downhole tool. The example method also includes directing a pattern of light onto a target in the optical field of view via a light source of the imaging system and determining three-dimensional shape information of the target based on the light directed from the target and received via an image detection plane of the imaging system. The example method further includes determining a characteristic of the target based on the three-dimensional shape information.

Abstract: Remote sensing systems and methods for analyzing characteristics of moving drilling equipment, for example, rotational movement rate, longitudinal movement rate, geometry or combinations thereof, are provided. The sensing systems may include a detectable substance, marking equipment for marking the drilling equipment with the detectable substance, detection equipment for detecting the detectable substance and capturing data from which drilling equipment movement and/or geometry may be estimated, and processing equipment for estimating movement and/or geometry information from the captured data. The methods include marking the drilling equipment with a detectable substance, detecting the detectable substance, and using data captured during the detection to analyze movement and geometry of the drilling equipment.

Abstract: Example systems described herein to perform downhole fluid analysis include a depressurizer to be positioned downhole in a geological formation to depressurize a formation fluid in the geological formation. In such example systems, the depressurization of the formation fluid is to cause bubbles to nucleate in the formation fluid. Such example systems also include an imaging processor to be positioned downhole in the geological formation. In such example systems, the imaging processor is to capture imaging data associated with the formation fluid and to detect nucleation of the bubbles in the formation fluid based on the imaging data. Such example systems further include a controller to report measurement data via a telemetry communication link to a receiver to be located outside the geological formation. In such example systems, the measurement data includes a bubble point of the formation fluid calculated based on the detected nucleation of the bubbles.
