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.

Embodiment Construction

[0046] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0047] First, refer to figure 1 , the basic principle of the optical device for augmented reality of the present invention will be described.

[0048] figure 1 It is a figure showing the optical device for augmented reality disclosed in the said patent document 1 developed by the present applicant.

[0049] refer to figure 1 The image emitting unit 30 is a unit for emitting image light corresponding to an augmented reality image, and may be implemented as a small display device, for example. The reflecting part 20 reflects the image light emitted from the image emitting part 30 toward the user's pupil to provide an augmented reality image.

[0050] The optical unit 10 is a unit for transmitting at least a part of visible light, and may be, for example, a spectacle lens, and the reflective part 20 is embedded therein. The frame portion 40 is a unit that fi...

Abstract

The present invention relates to an optical device for augmented reality, and provides an optical device for augmented reality. The optical device comprises an optical means that transmits at least a portion of a visible light; a reflecting unit disposed inside the optical means; and an image emitting unit which emits image light corresponding to an image for augmented reality towards the inside of the optical means, wherein the image light corresponding to the image for augmented reality and emitted from the image emitting unit is reflected at least once inside the optical means and thereby delivered to the reflecting unit, and the reflecting unit provides a user with the image for augmented reality by reflecting the delivered image light towards the pupils of the eyes of the user.

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 by using a reflective structure and a small reflective part. 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 pr...
