Some embodiments provide a system which includes a layered transparent surface which includes a UV absorption layer configured to be located between a user environment and an external environment and a phosphor layer configured to be located between the user environment and the UV absorption layer. An image projection system can project an ultraviolet image upon the phosphor layer, which can generate a visual image based on a fluorescent reaction of the phosphor layer to the ultraviolet image which can be perceived by a user in the user environment. The image projection system can include a plurality of image projection systems which can project separate images on separate projection fields, which can result in the phosphor layer generating an image which can be perceived by a user, in the user environment, as a stereoscopic image.

Embodiments regard fabrication of air gap regions in multicomponent lens systems. An embodiment of an apparatus includes a first lens, the first lens including a pattern of photoresist material; a second lens bonded with the first lens by the photoresist material; and an air gap region between the first lens and the second lens. The photoresist pattern defines the air gap region between the first lens and the second lens.

A composite pane includes an outer pane having outer and inner surfaces, a first thermoplastic intermediate layer, a hologram element including a first set of holograms produced in one or more layers of a holographic material, wherein the first set of holograms includes a blue hologram that is activatable by blue light having a wavelength in a first range and is not responsive to light of other wavelengths, a green hologram that is activatable by green light having a wavelength in a second range and is not responsive to light of other wavelengths, and a red hologram that is activatable by red light having a wavelength in a third range and is not responsive to light of other wavelengths, an inner pane, and a color-selective optical filter for selective absorption of light.

A light scanning device includes a light source that emits laser light, a mirror device that includes a movable mirror swinging about at least one axis and directionally changes the laser light emitted from the light source by reflecting the laser light using the movable mirror, and a condensing optical system that condenses the laser light directionally changed by the mirror device. The condensing optical system includes a half-silvered mirror that has a concave surface, and a diffusion plate in which a plurality of micromirrors that diffuse the laser light transmitted through the half-silvered mirror from the concave surface side are formed.

Aspects of the present invention relate presentation of digital content, in a see-through display, representing a known location in an environment proximate to a head worn computer.

An imaging system includes a light source configured to generate a light beam. The system also includes first and second light guiding optical elements having respective first and second entry portions, and configured to propagate at least respective first and second portions of the light beam by total internal reflection. The system further includes a light distributor having a light distributor entry portion, a first exit portion, and a second exit portion. The light distributor is configured to direct the first and second portions of the light beam toward the first and second entry portions, respectively. The light distributor entry portion and the first exit portion are aligned along a first axis. The light distributor entry portion and the second exit portion are aligned along a second axis different from the first axis.

The disclosure relates to providing of a display that can provide content through either a virtual image from a heads-up-display or a transparent display physically adhered to the back surface of the heads-up-display. The aspects disclosure herein also relate to providing a detection of an input, and in response to detection, switching the combined display from a first mode to a second mode.

One variation of a system for serving augmented visual content to a user includes: a visor including a substrate of a transparent material and a reflective coating applied across the substrate, configured to selectively reflect visible light within a first reflection channel, and configured to transmit wavelengths of visible light outside of the first reflection channel, wherein the first reflection channel spans a first band of wavelengths; a projection system configured to project visual content in a first output channel onto an interior surface of the visor, the first output channel including a first peak-power wavelength of visible light within the first reflection channel and excluding wavelengths of visible light outside the first reflection channel; and a support structure configured to locate the visor on the user's head with the visor in a field of view of the user and configured to locate the projection system relative to the visor.

A light blocking screen includes a liquid crystal array mounted to a window. The liquid crystal array has a plurality of liquid crystal (LC) pixels, each of which is selectively darkenable. A controller is operatively connected to the liquid crystal array and configured to darken a set of the LC pixels, such that the darkened set of LC pixels limits light passage through the window in one or more selected areas. The LC pixels need not limit light passage through the entire window. The controller may determine a location of a glare source relative to the window and a location of a user proximate the window, and then darken the set of the LC pixels in an area between the glare source and the user, such that the glare source is limited from shining onto the user. The screen may be incorporated into vehicles or buildings.

The first optical element 10 and the second optical element 20 are spaced away from each other in an effective area through which a light beam passes, and satisfy the following condition (1):
0<D.sub.MAX/f≦0.3  (1)
where D.sub.MAX is the maximum value of a distance as measured in the effective area through which the light beam passes on a section including a center chief ray of the light beam in a direction parallel with the center chief ray between the second surface 12 of the first optical element 10 and the first surface 21 of the second optical element 20, and f is the focal length of the decentered optical system 1.
