Abstract: A system includes an inspection robot having a number of payloads, a number of arms mounted to the payloads, and a number of sleds mounted to the arms. The system includes a number of sensors, each mounted to a corresponding sled, such that the sensor is operationally coupleable to an inspection surface in contact with a bottom surface of the corresponding sled. A couplant chamber is provided within at least two of the sleds, the couplant chamber between a transducer of a sensor and the inspection surface. The system includes a biasing member for each of the arms, where the biasing member provides a down force on the corresponding sled.

Abstract: Systems, devices, and methods for beam combining are described. A monolithic beam combiner includes a solid volume of optically transparent material having two orthogonally positioned planar input surfaces, an output surface, and at least two planar dichroic reflectors positioned within the solid volume. Multiple light sources input light into the solid volume through the two planar input surfaces such that each light beam from a respective source is initially incident on one of the planar dichroic reflectors. The light is reflected by and transmitted through the reflectors and an aggregate beam is created. Because the reflectors are within an optically transparent material the beam combiner can be made more compact than a conventional beam combiner. This monolithic beam combiner is particularly well suited for use laser projectors and in wearable heads-up displays that employ laser projectors.

Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays (“WHUDs”) are described. A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an optical splitter positioned in the optical path therebetween. The optical splitter receives light signals generated by the SLP and separates the light signals into N sub-ranges based on the point of incidence of each light signal at the optical splitter. The optical splitter redirects the light signals corresponding to respective ones of the N sub-ranges towards the holographic combiner effectively from respective ones of N spatially-separated virtual positions for the SLP. The holographic combiner converges the light signals to respective ones of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.

Abstract: Systems, devices, and methods for optical splitters are described. An optical splitter includes a transparent polygonal structure having an input side to receive light from a light source and an output side that is segmented into multiple facets. Each facet is engineered to provide a respective planar surface that is oriented at a different angle in each of at least two spatial dimensions relative to the other facets in order to refract and route a respective portion of the light along a respective set of optical paths. The input side may be faceted as well to further refine the optical paths. A particular application of the polygonal structure in an optical splitter providing eyebox expansion by exit pupil replication in a scanning laser-based wearable heads-up display is described in detail.
