Implementations are described of an eyepiece for a head wearable display. The eyepiece includes a curved lightguide for guiding display light via total internal reflection between a peripherally-located input surface and a viewing region and an output coupler disposed across the viewing region to redirect the display light towards an eyeward direction for output from the curved light guide. The output coupler has an optical axis and has a set of reflective surfaces that includes at least two individual reflective surfaces to reflect incident display light toward the eyeward direction in at least two different directions relative to the optical axis of the output coupler. Other embodiments are disclosed and claimed.

An apparatus having optical waveguides for providing a large FOV is disclosed. A first light engine projects light into an input diffractive coupler of a first waveguide at a first central angle. An output coupler of the first waveguide projects the light out of the first optical waveguide. A second light engine projects light into an input diffractive coupler of a second waveguide at a second central angle that is greater than the first central angle. An output coupler of the second waveguide projects the light out of the second optical waveguide to intersect with the light projected out of the first optical waveguide. The first waveguide may be used to project a first part of an image into a central portion of a user's vision. The second waveguide may be used to project a second part of the image into a peripheral portion of the user's vision.

Compact and low mass augmented and fully virtual head mounted display designs are disclosed. The disclosed displays employ a display located between the eye and the main optical element of the head mounted display. These designs additionally afford the ability to support augmented reality displays because the user can see both the virtual image from the display and the real world if desired. The designs use semi-transparent displays where either the display emits circularly polarized light or the displays which emits light from one surface or the view of the display directly from the eye is obscured.

A head-mounted equipment capable of displaying images includes: a head-worn member, a visor, a face-worn member and a display. The head-worn member has a front edge, and the visor is attached to the front edge of the head-worn member and is partially reflective and partially transparent. The face-worn member has a wearing surface and an opposite mounting surface, and the display is mounted on the mounting surface of the face-worn member to project an image to the visor.

A spectacle lens for a display device may include a front side, a rear side, a coupling-in section and a coupling-out section. The coupling-out section includes at least two reflective deflecting surfaces arranged next to each other. The spectacle lens guides light bundles of pixels of the generated image to the coupling-out section in the spectacle lens and couples them out of the spectacle lens through the rear side. The spectacle lens includes a main part with the front and rear side, in which a recess extending from the rear side or from the front side to the surface structure is present, into which an insert element is inserted, the first end of which facing the surface structure is formed complementary to the surface structure, wherein the reflective deflecting surfaces lie between the surface structure of the main part and the first end of the insert element.

The present invention relates to a head-mounted display including a pair of headphones having a built-in speaker for outputting sound, a first arm rotatably coupled to the pair of headphones to display an image, a second arm coupled to the pair of headphones so as to relatively rotate with the first arm to cover or uncover a front surface of the first arm, and a control unit controlling the image output to the first arm and the sound output to the headphones according to positions of the first arm and the second arm.

An optical system is configured to form an enlarged image of a display surface of an image display element and includes, in order from a side of an exit pupil to a side of the display surface, a first half-transmissive reflective surface and a second half-transmissive reflective surface. The optical system has a first optical path on which light from the display surface transmits through the second half-transmissive reflective surface, is reflected by the first half-transmissive reflective surface, is reflected by the second half-transmissive reflective surface, transmits through the first half-transmissive reflective surface, and is guided to the exit pupil, and a second optical path on which light from the side of the exit pupil transmits through the first half-transmissive reflective surface, transmits through the second half-transmissive reflective surface, and is guided to an image sensor.

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.

According to the invention, provided are a windshield glass including: a projected image display portion on which a projected image is displayed with projected light; and a second glass plate, an intermediate layer, and a first glass plate provided in this order from an incidence side of the projected light, in which the intermediate layer has a wedge-shaped cross section, the projected image display portion at least includes a half-mirror film, and the half-mirror film includes a cholesteric liquid crystal layer, and a head-up display system including the windshield glass. According to the windshield glass of the invention, it is possible to perform a display of a projected image having high brightness, in which generation of a double image is reduced.

An enhanced vision system includes a first optic subsystem and a transparent photodetector subsystem disposed within a common housing. The first optic subsystem may include passive devices such as simple or compound lenses, active devices such as low-light enhancing image intensifiers, or a combination of passive and active devices. The transparent photodetector subsystem receives the visible image exiting the first optic subsystem and converts a portion of the electromagnetic energy in the visible image to a signal communicated to image analysis circuitry. On a real-time or near real-time basis, the image analysis circuitry detects and identifies structures, objects, and/or individuals in the visible image. The image analysis circuitry provides an output that includes information regarding the structure, objects, and individuals to the system user contemporaneous with the system user viewing the visible image.
