Publication number: 20230161159Abstract: Disclosed embodiments are related to an optical system of an augmented reality (AR) head-up display (HUD) devices. The implementation of disclosed optical system in AR HUD devices improves visual ergonomics by providing enhanced stereoscopic depth of field (SDoF). The SDoF is created by the formation of a proper shape and spatial orientation of a virtual image surface (VIS) where a convex side is oriented towards a user or observer. When such optical systems of AR HUD devices are implemented in a vehicle, the improved visual ergonomics provides improved driving comfort and safety.Type: ApplicationFiled: December 9, 2021Publication date: May 25, 2023Applicant: WAYRAY AGInventors: Andrey BELKIN, Kseniia Igorevna LVOVA, Vitaly PONOMAREV, Anton SHCHERBINA, Mikhail SVARYCHEUSKI

Publication number: 20230161158Abstract: An optical system includes a picture generation unit (PGU), a correcting optical unit configured to create, in a direction of a horizontal field of view (HFoV), a monotonic variation of an optical path length of light rays propagating from the PGU, and a combiner configured to redirect light rays propagating from the correcting optical unit toward an eye box, producing one or more virtual images observable from the eye box. The optical system provides a virtual image surface inclined in the direction of the HFoV for displaying the virtual images. The virtual image surface has a non-zero angle between projections on a horizontal plane defined by a first axis perpendicular to the virtual image surface and extending through an arbitrary intersection point on the virtual image surface, and a second axis parallel to a line of sight and extending from the eye box through the intersection point.Type: ApplicationFiled: December 9, 2021Publication date: May 25, 2023Applicant: WAYRAY AGInventors: Andrey Mikhailovich BELKIN, Kseniia Igorevna LVOVA, Vitaly PONOMAREV, Anton Alekseevich SHCHERBINA, Mikhail SVARYCHEUSKI

Publication number: 20230096336Abstract: An optical system includes a picture generation unit configured to output an optical image, a correcting optical element, and a combiner. The shape of the combiner and the shape of the correcting optical element are correlated such that the optical system can produce augmented reality at relatively long distances (e.g., 1.5 meters or more). The correcting optical element includes a convex reflective surface configured to reflect the optical image output by the picture generation unit. The combiner has a concave reflective surface and a convex transparent surface. The concave reflective surface of the combiner is configured to reflect the optical image reflected by the correcting optical element toward an eye box, which represents an eye pupil of the observer. The convex transparent surface of the combiner is configured to permit external light to pass through the combiner and combine with the optical image reflected by the correcting optical element.Type: ApplicationFiled: September 29, 2021Publication date: March 30, 2023Applicant: WayRay AGInventors: Andrey Mikhailovich Belkin, Oleg Igorevich Bushmanov, Vitaly Andreevich Ponomarev, Anton Alekseevich Shcherbina, Mikhail Aleksandrovich Svarycheuski

Publication number: 20220057644Abstract: Devices for applying vibration and/or sliding motion to speckle diffusers are provided. A speckle diffusion device comprises at least one speckle diffuser element, one free form torsion spring with an axis of rotation, and at least one actuator. One end of the torsion spring includes an interaction element to interact with the actuator. The actuator actuates motion of the speckle diffusion element via the interaction element attached to the spring. The spring may also limit motion of the speckle diffuser element. The speckle diffusion device may be implemented or employed in various optical systems/devices. The speckle diffusion device may be easily adapted to accommodate various systems with various dimensions and geometry. Other embodiments may be disclosed and/or claimed.Type: ApplicationFiled: November 1, 2021Publication date: February 24, 2022Applicant: WAYRAY AGInventors: Aleksandr BOBRYSHEV, Irina GAVRILOVICH, Vitaly PONOMAREV

Patent number: 10444518Abstract: Indication systems for the drivers of vehicles and cars include a data display device that combines two optical systems of the image display—the virtual image display system and the real image display system. The display device may be configured to provide a maximum of displayed information and to ensure safe driving, by controlling the level of details and the content of the data displayed for the vehicle driver, depending on the speed, and by choosing the optical system of data display to minimize the accident risk. Image quality and safe driving may be improved due to the combination of two systems and control of the level of detail of displayed data.Type: GrantFiled: March 31, 2014Date of Patent: October 15, 2019Assignee: WAYRAY AGInventors: Vitaly Andreevich Ponomarev, Sergey Aleksandrovich Dyakov, Anton Alekseevich Shcherbina
