Abstract: Hand-held image scanner apparatus may comprise a body having first and second side walls positioned in spaced-apart relation so that the second side wall is located a spaced distance from the first side wall. The body also includes a convex face portion that extends between the first and second side walls and defines a contact axis that extends along a lateral direction and that is located longitudinally between the first and second side walls. The convex face portion allows the body to be tilted about the contact axis when the convex face portion is in contact with an object to be scanned. An image sensing system mounted within the body is responsive to image light reflected by the object being scanned and produces an image signal based on the image light. The image sensing system is optically coupled to an image light opening in the convex face portion of the body so that image light passing through the image light opening is received by the image sensing system.

Abstract: In embodiments of laser illumination scanning, an imaging unit includes a linear array of spatial light modulators that direct light in a direction perpendicular to an imaging scan direction. The lasers each emit the light through a diffractive optic that uniformly illuminates the spatial light modulators, and a scanning mirror then scans the spatial light modulators to generate a two-dimensional image for display. The lasers can include red, green, and blue lasers for RGB illumination of the spatial light modulators, which can be implemented as reflective liquid crystal on silicon (LCOS), transmissive LCOS, or as micro-electro-mechanical systems (MEMS) mirrors.

Abstract: In embodiments of pixel opacity for augmented reality, a display lens system includes a first display panel that displays a virtual image generated to appear as part of an environment viewed through optical lenses. A second display panel displays an environment image of the environment as viewed through the optical lenses, and the environment image includes opaque pixels that form a black silhouette of the virtual image. The display lens system also includes a beam-splitter panel to transmit light of the environment image and reflect light of the virtual image to form a composite image that appears as the virtual image displayed over the opaque pixels of the environment image.
