Problems solved by technology

[0003] However, for eyepieces with large field of view used in micro-display head-mounted systems, chromatic aberration of magnification, field curvature, and astigmatism are all aberrations that affect the imaging quality, so a suitable optical design is urgently needed to completely solve the above problems

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 It is a schematic diagram of the working principle of the head-mounted visual device. The human eye watches the display through the micro-display eyepiece. The light emitted by the display passes through the eyepiece and forms a huge virtual image at a distance of 5m from the human eye, which is then received by the human eye.

[0039] When designing the optical system of the head-mounted visual device, reverse tracking is adopted, so that the display screen of the head-mounted visual device is located at the image plane of the optical system, and the aperture is located at the pupil of the human eye; the display screen adopts M-OLED Display, used to eliminate graining defects.

[0040] The optical system adopts a spec...

Abstract

The invention discloses an eyepiece, a headset eyepiece system and a piece of micro-display headset equipment. The eyepiece comprises a first positive lens, a second positive lens and a third negative lens which are orderly arranged along the light; the first positive lens is provided with a first surface of a convex image space and a second surface of the convex image space; the second positive lens is provided with a third surface of the convex image space and a fourth surface of the convex image space; the third negative lens is provided with a fifth surface of a concave image space and a sixth surface of the concave image space. Lens combination of spherical glass and aspheric plastic is rationally designed according to an optical system in the technical scheme, so that images of chromatic difference of magnification, field curvature and astigmatism aberration are thoroughly corrected when a wide range angle is obtained, and the imaging quality of the system is guaranteed; and the technical scheme further meets the requirements on miniaturization, light weight and wide range angle.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an eyepiece, a head-mounted eyepiece system and a micro-display head-mounted device. Background technique [0002] At present, micro-display head-mounted systems are widely welcomed by consumers due to their small size and light weight. In particular, the large field of view of the system can create a shocking visual effect for the user, making the user feel like watching a movie in a movie theater projection hall. [0003] However, for eyepieces with large field of view used in micro-display head-mounted systems, chromatic aberration of magnification, field curvature, and astigmatism are all aberrations that affect the imaging quality, so a suitable optical design is urgently needed to completely solve the above problems. Contents of the invention [0004] The invention provides that aberrations such as chromatic aberration of magnification, curvature of field and astigmatis...
