Art exhibition device and a video picture exhibition method which are capable of providing renditions by a spatial image and a projected image, in combination are provided. The exhibition device includes a display portion configured to image-form a spatial image; and a projector configured to project a video picture onto an object. The video picture exhibit ion method using the exhibition device provides a video picture related to the spatial image projected from the projector disposed in a position hang over the display portion toward an upper surface of the display portion. The display portion is configured to image-form a video picture displayed on a display surface of a display disposed in an attitude inclined under a micromirror array through the micromirror array disposed in light-transmissive fashion as a spatial two-dimensional video picture standing up obliquely in a spatial position lying over the micromirror array.

In one example, a method comprises forming a first layer on a substrate surface, forming an opening in the first layer, forming a second layer on the first layer and in the opening, and forming a photoresist layer on the second layer, in which the photoresist layer has a first curved surface over a first part of the first layer and over the opening. The method further comprises etching the photoresist layer and a second part of the second layer over the first part of the first layer to form a second curved surface on the second part of the second layer, and forming a mirror element and a support structure in the second layer, including by etching a third part of the second layer and removing the first layer.

Disclosed is an eyewear display device for displaying a virtual image in a field of view of a user, comprising a frame unit, a line-shaped screen unit attached to the frame unit for emitting light as computer-generated image information in a first direction; at least two partially transparent beam splitter units attached to the frame unit, designed to be operated as scanner units at a defined scanner frequency, for deflecting the light emitted in the first direction from the screen unit into a second directional range corresponding to the field of view of the user when the eyewear display device is used as intended; to provide an eyewear display device for display, AR glasses, by which the virtual image is displayed in as large a sub-area of the field of view as possible and the form factor of which corresponds as closely as possible to that of ordinary glasses.

A light projection system, including a light source to provide an output beam of light, an angular light modulator (ALM) comprising a plurality of pixels, each pixel having an ON state and an OFF state, the ALM positioned to receive output beam on the plurality of pixels, and a processor coupled to the ALM. The processor is programmed to control a first set of the pixels to transition between the OFF state and the ON state while the beam is incident on the pixels. An amount of light is selectively directed in a direction by the first set. The processor is also programmed to control a second set of the plurality of pixels to remain in the OFF state while the beam is incident on the plurality of pixels. As a result, the ALM operates as a spatial light modulator and an angular light modulator of the beam of light.

Implementations of a compressive light field projection system are disclosed herein. In one embodiment, the compressive light field projection system utilizes a pair of light modulators, such as digital micromirror devices (DMDs), that interact to produce a light field. The light field is then projected via a projection lens onto a screen, which may be an angle expanding projection screen that includes a Fresnel lens for straightening the views of the light field and either a double lenticular array of Keplerian lens pairs or a single lenticular, for increasing the field of view. In addition, compression techniques are disclosed for generating patterns to place on the pair of light modulators so as to reduce the number of frames needed to recreate a light field.

A volumetric display capable of high-speed image presentation includes a resonance-type liquid lens having a focal length that is periodically adjusted using resonance of a liquid. An image projector projects an image toward a viewpoint position of a user via the resonance-type liquid lens. Further, the image projector projects an image toward the viewpoint position within a shorter time period than one-tenth of a variation cycle of the focal length. The image projector includes an LED and a DMD, for example.

A device and methods for displaying representations of objects, solids, and surfaces volumetrically in a medium containing one or more photochromic compounds comprising at least one UVA light source arranged to project a beam of UVA radiation and irradiate at least one portion of a display volume incorporating at least one display medium which includes at least one photochromic compound. The irradiance of the irradiated portion of the display medium being sufficient for clear-to-colored transitions of voxels of the display medium from a transparent state to a colored state. After a time period after the irradiation, the irradiated voxels activated in the colored state transition by a colored-to-clear transition into the transparent state.
