Problems solved by technology

Among them, the geometric optics scheme is the main idea. Compared with the diffraction scheme, it has the characteristics of mature technology, convenient device processing, and small assembly tolerance requirements. It is currently favored by many manufacturers such as Google, Lenovo, and Microsoft. Limited to the overall size, weight / price requirements of the light source device and the AR system, there are common problems that the size, price, field of view, performance, and observation distance cannot be taken into account, and the displayed content is easy to leak, and the confidentiality is poor; An additional myopia lens is required to be used together with the optical system
These disadvantages reduce the experience of using augmented reality wearable devices

Abstract

The invention provides a multiplexing light source binocular optical display system and wearable equipment, and belongs to the technical field of AR. The multiplexing light source binocular optical display system comprises a display, a light splitting module, a first optical module, a second optical module, a third optical module and a fourth optical module, wherein the light splitting module is arranged on a light emitting path of the display, and processes the light incident from the display to obtain first emergent light and second emergent light; the first optical module is arranged on thelight path of the first emergent light, and the second optical module is arranged on the light path of the first optical module; and the third optical module is arranged on the light path of the second emergent light, and the fourth optical module is arranged on the light path of the third optical module. The system is small in size, good in imaging quality, free of display light leakage and goodin confidentiality. The wearable equipment is convenient to wear and good in universality, can adapt to myopic users through a compensating mirror, and greatly improves the wearing experience of theusers.

Description

technical field [0001] The invention belongs to the field of AR technology, and in particular relates to a binocular optical display system with a multiplexed light source and a wearable device. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that projects an image in front of the human eye through a transmission device and superimposes the real scene and the virtual scene. In this way, completely new visual experiences can be given and new fields of application can be enhanced or created. Transmissive optical display system is one of the core technologies in the field of augmented reality. At present, wearable devices using enhanced display technology have been widely used in gaming, retail, education, industry, medical and other fields. [0003] At present, the transmissive optical display technology can be divided into geometrical optics schemes: Birdbath, ordinary reflective prisms, free-form surface prisms and other schemes, and...
