The present invention comprises a compact optical see-through head-mounted display capable of combining, a see-through image path with a virtual image path such that the opaqueness of the see-through image path can be modulated and the virtual image occludes parts of the see-through image and vice versa.

Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

Disclosed are systems and methods for manufacturing energy relays for energy directing systems and Transverse Anderson Localization. Systems and methods include providing first and second component engineered structures with first and second sets of engineered properties and forming a medium using the first component engineered structure and the second component engineered structure. The forming step includes randomizing a first engineered property in a first orientation of the medium resulting in a first variability of that engineered property in that plane, and the values of the second engineered property allowing for a variation of the first engineered property in a second orientation of the medium, where the variation of the first engineered property in the second orientation is less than the variation of the first engineered property in the first orientation.

A projection optical system applicable to a head-up display device mounted on an automobile includes an image generation unit, a reflection unit, a double-telecentric lens, a light splitting device, and an imaging lens that are successively arranged in a light exit direction. The light splitting device needs to be arranged on an image side of the double-telecentric lens and configured to reflect a light beam for imaging in light beams emitted by the image generation unit. The double-telecentric lens is configured to adjust a size of the projection image. The imaging lens is configured to adjust a virtual image distance of the projection image and output the light beams of the projection image to achieve projection imaging.

The invention provides an autonomous vehicle with a video camera that merges images taken a different light levels by replacing saturated parts of an image with corresponding parts of a lower-light image to stream a video with a dynamic range that extends to include very low-light and very intensely lit parts of a scene. The high dynamic range (HDR) camera streams the HDR video to a HDR system in real time—as the vehicle operates. As pixel values are provided by the camera's image sensors, those values are streamed directly through a pipeline processing operation and on to the HDR system without any requirement to wait and collect entire images, or frames, before using the video information.

A coupling-in optical arrangement is configured for coupling light waves into a light-waves transmitting substrate by total internal reflection. The light-waves transmitting substrate has at least a first major external surface and a second major external surface. At least one of the first or second major external surfaces is coated with a coating that compensates for non-uniformity of the light-waves transmitting substrate. The light-waves transmitting substrate is formed from a plurality of transparent plates interleaved with a plurality of optical elements such that the transparent plates and the optical elements alternate along the light-waves transmitting substrate. Each of the transparent plates is coated with a partially reflecting coating, thereby forming a plurality of partially reflecting surfaces, which are configured for coupling light waves out of the light-waves transmitting substrate.

Endoscopic camera head devices and methods are provided using light captured by an endoscope system. Substantially afocal light from the endoscope is manipulated and split. After passing through focusing optics, another beamsplitter is used to split the light again, this time in image space, producing four portions of light that may be further manipulated. The four portions of light are focused onto separate areas of two image sensors. The manipulation of the beams can take several forms, each offering distinct advantages over existing systems when individually displayed, analyzed and/or combined by an image processor.

A light source optical system includes: a first optical system configured to guide a first light beam having a first wavelength emitted from a light source to a wavelength conversion element; the wavelength conversion element configured to convert the first light beam into a second light beam having a second wavelength different from the first wavelength, and emit the second light beam; and a second optical system through which the second light beam emitted from the light conversion element passes. The second optical system includes a light guide element configured to guide a portion of the second light beam from one end surface of the light guide element to the other end surface of the light guide element to separate the portion of the second light beam from the second light beam.

An optical assembly includes a first reflector and a second reflector. The first reflector is positioned to receive first light having a first polarization and provide the first light toward a first direction, and receive second light having the first polarization and provide the second light toward a second direction. The second reflector is positioned to receive the second light from the first reflector and reflect the second light back toward the first reflector. The first reflector receives light having a second polarization, having been reflected by the second reflector, and provide the light toward the first direction so that a first image corresponding to the first light and a second image corresponding to the second light are projected on a common image plane where at least a portion of the second image is located between two portions of the first image.

An illumination system includes a surface configured to have an imaging target placed thereon, a light source, a beam splitter and at least a first mirror. The beam splitter is configured to split the beam of light from the light source and the first mirror is configured to reflect a first beam from the beam splitter onto the surface with the imaging target. An imaging system includes an imaging surface configured to have an imaging target placed thereon, a mirror, and a capturing device. The capturing device is configured to capture an image of the imaging target through a path of emitted light that extends from the imaging target, reflects off of the mirror, and to the capturing device. The mirror, the capturing device, or both are configured to move in a diagonal direction with respect to the imaging surface to reduce a length of the path of emitted light. Systems and methods to calibrate an imaging system to remove or reduce non-uniformities within images of samples due to imaging system properties.
