Optical device for augmented reality

Abstract

The present invention relates to an optical device for augmented reality, comprising: an optical means for at least partially transmitting visible light; and a refection part group including a plurality of reflection parts arranged in a row along the first direction corresponding to any one linear direction on the surface of or inside the optical means, wherein the reflection parts reflect, to the pupil of a user's eye, image light exiting an image-emitting part for emitting image light corresponding to an augmented reality image.

Description

technical field [0001] The present invention relates to an optical device for augmented reality, and relates to an optical device for augmented reality capable of providing a user with augmented reality images using a plurality of small reflection parts. Background technique [0002] As we all know, augmented reality (Augmented Reality, AR) refers to superimposing and providing virtual images or images generated by computers or the like on actual images in the real world. [0003] In order to realize such augmented reality, an optical system is required that can superimpose and provide a virtual image or image generated by a device such as a computer on an image of the real world. As such an optical system, it is well known to use an optical unit such as a prism that reflects or refracts a virtual image by using a head mounted display (HMD, Head Mounted Display) or a glasses-type device. [0004] However, a device using such an existing optical system has problems in that i...

Problems solved by technology

[0004] However, the device using such an existing optical system has the following problems: it is inconvenient for the user to wear due to its complex structure and considerable weight and volume, and the manufacturing process is also complicated, resulting in high manufacturing cost

However, these techniques also have the problem that in order to adjust the focus, the user needs to perform additional operations or require hardware and software such as an additional processor for controlling the focus.

However, since the applicant's technique uses a small reflector, it has a limitation of a narrow field of view.
