An optical system including two optical systems, each optical system including at least two reflectors and a stop. Each of the optical systems is configured to focus light. Each of the at least two reflectors is configured to reflect the light.

Display systems, such as near eye display systems or wearable heads up displays, may include a laser projection system having an optical engine and an optical scanner. Light output by the optical engine may be directed into the optical scanner as two angularly separated laser light beams. The angularly separated laser light beams may overlap at an entrance pupil plane along a first dimension at a first scan mirror of the optical scanner, or at a location between the first scan mirror and an optical relay of the optical scanner. The angularly separated laser light beams may overlap at an exit pupil plane along the first dimension at a second scan mirror of the optical scanner or at an incoupler of the laser projection system.

A laser projection system utilizes a waveguide having a narrow incoupler for double-bounce mitigation and form factor reduction. An optical scanner includes an optical relay positioned in between two scan mirrors. The first scan mirror scans laser light into the optical relay in a first dimension, and the optical relay and converges the scanned laser light towards a second scan mirror. The second scan mirror scans laser light along a second dimension substantially perpendicular to a path over which the laser light is scanned across the second scan mirror, and the convergence introduced by the optical relay causes the laser light to be scanned as a line or arc path of an exit pupil plane that is coincident with the incoupler. The optical relay may include one or more lenses or may be a monolithic molded structure, which may be an Offner-style relay or a molded reflective relay.

The present disclosure relates to optical systems. An example optical system includes at least one primary optical element configured to receive incident light from a scene and a plurality of relay mirrors optically coupled to the at least one primary optical element. The optical system also includes a lens optically coupled to the plurality of relay mirrors, and an image sensor configured to receive focused light from the lens. The image sensor includes a first light-sensitive area and a second light-sensitive area. The primary optical element, the plurality of relay mirrors, and the lens interact with the incident light to form a first focused light portion and a second focused light portion. The first focused light portion forms a first image portion of the scene on the first light-sensitive area and the second focused light portion forms a second image portion of the scene on the second light-sensitive area.

Described are two mirror scanning projectors employing a collimated laser beam directed to a first mirror that scans in one direction, an optical relay system, and a second mirror that scans in a perpendicular direction from the first mirror to provide two dimensional scanning of the laser beam.

A virtual image display device of the invention includes an image display element configured to emit image light, a relay optical system configured to generate an intermediate image of the image light emitted from the image display element, and an ocular optical element configured to reflect the intermediate image toward a position assumed to be a position of an eye of an observer to generate an enlarged virtual image. The relay optical system includes a prism, and the prism includes a first bending surface including a bending surface and serving as an incident surface, a second bending surface including a bending surface and serving as an emission surface, and a reflecting surface configured to reflect, toward the second bending surface, the image light incident from the first bending surface.

A display system includes a display device, a first mirror, and a second mirror. The display device includes a display surface that displays a first image. Light emitted by the display device is incident directly or indirectly on the first mirror. The first mirror reflects the light incident. The light reflected by the first mirror is directly or indirectly incident on the second mirror. The second mirror reflects, toward an eye-box, the light incident. The light reflected by the second mirror enters an eye of an observer present within the eye-box to display, on the eye of the observer, a second image based on the first image. The first mirror is a Fresnel mirror.
