Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingl...

Abstract

The invention discloses an optical system and a virtual reality device having the same. The optical system sequentially includes a first lens, a folding mirror group, and a display unit along the optical axis; the first lens includes a first surface away from the display unit and a surface close to the display unit. The second surface; the effective aperture of the first lens is smaller than the effective aperture of the folding mirror group, and the first lens is used to reduce the effective aperture of the optical system; the folding mirror group includes a third surface and a fourth surface; the incident light emitted by the display unit is from The fourth surface enters the folding mirror group and is reflected between the third surface and the fourth surface. When the incident light passes through the third surface for the second time, it exits the third surface and enters the first lens from the second surface. The first surface exits the first lens and transmits to the pupil. The present invention provides an optical system and a virtual reality device with the same, aiming at solving the problem of large size and small viewing angle of the virtual reality device in the prior art.

Description

technical field [0001] The present invention relates to the technical field of optical imaging, in particular to an optical system and a virtual reality device having the same. Background technique [0002] In the field of virtual reality (Virtual Reality, VR) technology, virtual reality devices are gradually developing in the direction of miniaturization, light weight, and large field of view. The existing VR optical system is usually composed of a display unit and a single lens. In this case, in order to avoid the size of the VR device from being too large, the field of view of the VR device is usually less than 110 degrees, and the best field of view of the human eye. The angle is usually about 120 degrees, which makes the VR device unable to meet the best needs of human eyes. When the field of view of the VR device is increased, the size of the display unit and the lens needs to be correspondingly increased, thereby increasing the size of the VR device. size of. SUMMA...
