An optical apparatus includes an image source, a relay optical system, and an optical processing system. The image source is configured to display an image. The relay optical system is configured to project the image displayed by the image source to the optical processing system, and to image at infinity. The optical processing system is configured to project incident light from the relay optical system in a same direction to at least two preset directions sequentially.

A diffractive optic reflex sight (DORS) is provided for aiming devices in which a virtual image, such as a reticle, is produced and appears in the distance of a user's view when looking through the reflex sight. A light source illuminates a diffractive optical element (DOE) that includes a modulation pattern that generates a patterned illuminations corresponding with the virtual image. A reflective image combiner then reflects the patterned illumination so that the virtual image appears in the distance of the viewer's view. The DORS optical design system is mechanically and optically stable for precision aiming across a range of environmental conditions and in different use scenarios or applications including use in rapidly changing temperatures, varying light conditions, and a wide range of user proficiencies. The DORS optical design system is a readily manufacturable aiming and sighting device for a wide range of applications from handguns to astronomical telescopes.

A method includes detecting at least one remote vehicle that is within a predetermined distance from the host vehicle, detecting that the light of the remote vehicle that is on, determining a luminous intensity of a light beam emitted by the light of at least one remote vehicle that is within the predetermined distance from the host vehicle, comparing the luminous intensity of the light beam emitted by the light of at least one remote vehicle to a predetermined threshold to determine whether the luminous intensity of the light beam emitted by the light is greater than the predetermined threshold in response to determining the luminous intensity of the light of at least one remote vehicle that is within the predetermined distance from the host vehicle, and dimming at least a portion of the windshield of the host vehicle.

Disclosed are systems and methods for superimposing a virtual image on a real-time image. A system for superimposing a virtual image on a real-time image comprises a real-time image module and a virtual image module. The real-time image module comprises a magnification assembly to generate a real-time image of an object at a first location and a first depth, with a predetermined magnification. The virtual image module generates a virtual image by respectively projecting a right light signal to a viewer's right eye and a corresponding left light signal to a viewer's left eye. The right light signal and the corresponding left light signal are perceived by the viewer to display the virtual image at a second location and a second depth. The second depth is related to an angle between the right light signal and the corresponding left light signal projected to the viewer's eyes. The second depth may be approximately the same as the first depth.
