An ultra-high-definition, internal focus virtual reality optical system

Abstract

The invention discloses an ultra-high-definition internal focusing virtual reality optical system. The system comprises an aperture (100), and a first lens (1), a second lens (2), a third lens (3), a fourth lens (4) and a display screen (200) are sequentially arranged behind the aperture (100); the first lens (1) adopts a bi-convex aspherical lens, the second lens (2) adopts a crescent-shaped aspherical lens, the third lens (3) adopts a bi-convex aspherical lens, and the fourth lens (4) adopts a crescent-shaped aspherical lens; the first lens (1) and the second lens (2) are bound together through optical glue to form a glued lens set (300), and the glued surface bends towards the aperture (100). The ultra-high-definition internal focusing virtual reality optical system is simple in structure, high in definition, large in view field angle and wide in application range.

Description

【Technical field】 [0001] The invention relates to an optical system, more specifically to an ultra-high-definition, internal focusing virtual reality optical system. 【Background technique】 [0002] At present, virtual reality (Virtual Reality) is on the rise. The principle of VR glasses (virtual reality glasses) is similar to a magnifying glass, which is to enlarge the picture, and the human eye perceives the enlarged picture. The current mainstream product is one-piece, which can realize 3D effect, but the definition is poor, and the feeling of vertigo is strong when watching 3D images. Limited to too few parameters that can be optimized, it is difficult to improve the imaging quality of the lens. For example, aberrations such as dispersion distortion are almost impossible to eliminate with a single lens. Therefore, the lens group solution is the future VR helmet (the lens is mounted on the helmet The development trend of lenses in VR glasses). [0003] Therefore, the pre...

The current mainstream product is one-piece, which can achieve 3D effect, but the definition is poor, and the feeling of dizziness is strong when watching 3D images

Limited to too few parameters that can be optimized, it is difficult to improve the imaging quality of the lens. For example, aberrations such as dispersion distortion are almost impossible to eliminate with a single lens. Therefore, the lens group solution is the future VR helmet (the lens is mounted on the helmet The development trend of lenses in VR glasses)
