The head-mounted display device may provide good image quality and a large field of view.

Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

An optical system for a virtual retinal scan display. The optical system includes: a projector unit including a modulatable light source for generating at least one modulated light beam and including a movable deflection device for the light beam, a scanning projection of an image content being generatable from the at least one light beam as a result of the movement of the movable deflection device; a diverting unit, onto which the image content is projectable and which is configured to map the projected image content into an exit pupil and to guide it onto an eye of a user; an optical exit pupil shifting unit situated in an optical path of the light beam for spatially shifting the exit pupil of an eye box of the optical system in directions which extend at least essentially in parallel to an exit pupil plane of the exit pupil.

An optical system includes a light-guide optical element (LOE) (100) having a pair of parallel major external surfaces (102, 104) and a set of mutually-parallel reflector surfaces (106a, 106b, 106c) obliquely angled within the LOE. At least one of the reflector surfaces has high reflectivity for angles of incidence above 60 degrees to the normal and partial reflectivity for angles of incidence less than 35 degrees to the normal.

Disclosed are methods and devices for providing an image of a scene and then displaying an image of the scene on a display screen with a changed field of view. Some embodiments of the disclosed methods and devices are useful for increasing a human's visual perception, especially when such a human has a visual field deficiency.

The present technology provides a display device that is able to display information in a region larger than a visual field region and cause the information to be visually recognized. The display device according to the present technology includes a light irradiation system configured to apply light through a pupil on at least a region outside an ambient light irradiation region, within a larger region than the ambient light irradiation region, the larger region including the ambient light irradiation region, the ambient light irradiation region being a region in a retina on which ambient light is to be applied through the pupil. According to the present technology, it is possible to provide a display device that is able to display information in a region larger than a visual field region and cause the information to be visually recognized.

Provided is a waveguide-type display device including a waveguide, an input coupler provided on the waveguide and configured to transmit an image to travel into the waveguide, an output coupler provided on the waveguide and configured to output the image traveling in the waveguide to an outside of the waveguide, and a field-of-view (FOV) expander configured to output an image having an expanded FOV by deflecting and outputting the image output from the output coupler in a certain direction based on polarization characteristics of the image.

An optical system includes an image redirecting arrangement with at least two reflectors to direct a collimated image from an image projector so as to propagate within a light-guide optical element (LOE) in first and second directions, to be subsequently reflected by corresponding first and second sets of partially-reflecting internal surfaces towards a coupling-out optical arrangement. A part of a field of view (FOV) adjacent to the right side of the collimated image propagating in the first direction crosses a plane of one of the sets of partially-reflecting internal surfaces or a plane parallel to the major external surfaces, thereby forming self-overlap of a part of the collimated image in a region of the field of view which does not reach the eye of a user.
