Abstract: Multiview calibration is essential for accurate three-dimensional computation. However, multiview calibration can not be accurate enough because of the tolerances required in some of the intrinsic and extrinsic parameters that are associated with the calibration process, along with fundamental imperfections that are associated with the manufacturing and assembly process itself. As a result, residual error in calibration is left over, with no known methods to mitigate such errors. Residual error mitigation is presented in this work to address the shortcomings that are associated with calibration of multiview camera systems. Residual error mitigation may be performed inline with a given calibration approach, or may be presented as a secondary processing step that is more application specific. Residual error mitigation aims at modifying the original parameters that have been estimated during an initial calibration process.

Abstract: A light source or projector for a near-eye display includes a light source subassembly optically coupled to a waveguide concentrator. The light source subassembly may include several semiconductor chips each hosting an array of emitters such s superluminescent light-emitting diodes. The semiconductor chips may be disposed side-by-side, with their emitting sides or facets coupled to the waveguide concentrator, which provides a tight array of output light ports on a common output plane of the concentrator. The output diverging beams at the array of output light ports are coupled to a collimator, which collimates the beams and couples them to an angular scanner for scanning the collimated light beams together across the field of view of the display.

Abstract: This disclosure addresses the problem of preventing sediment laden water (“sediment slurry”) resulting from hydraulic collection of nodules from the seabed from entering the riser and lift system that carries the nodules to the surface as a slurry.
