Augmented reality technology is a field of virtual reality that synthesizes virtual objects or information in the real environment to make them look like objects that exist in the original environment. In other words, a virtual image is projected onto the actual image that the user is viewing and shown to the user.

Through augmented reality technology, users can feel the direct sense of reality experienced in the objective physical world and experience experiences that cannot be experienced in the real world. Augmented reality is distinct from virtual reality, where the actual surrounding environment cannot be seen, and its significance is in providing a better sense of reality and additional information through a mixture of the real environment and virtual objects.

Figure 1 is a diagram showing the configuration of an AR glass display device according to a first embodiment of the present invention.

Referring to FIG. 1, the AR glass display device 100 according to the first embodiment of the present invention includes a projector 110, a mirror 120, a first lens 130, a MEMS mirror 140, and a frame. It includes a Nell lens 150, an optical waveguide 160, a transflective concave mirror 170, and a control unit (not shown).

The AR glass display device 100 is implemented in the form of glass and is a device that outputs an augmented reality image to the wearer. At this time, the AR glass display device 100 can provide the wearer with an image with improved clarity by adjusting the ultra-wide angle and line width of 80° or more.

The projector 110 outputs an augmented reality image to the mirror 120a. The projector 110 includes a light source (not shown) for outputting an augmented reality image and outputs an augmented reality image.

The mirror 120a reflects the augmented reality image output from the projector 110 to the first lens 130.

The first lens 130 focuses the augmented reality image flowing into it (220). The first lens 130 focuses the augmented reality image, and the focused augmented reality image passes through the Fresnel lens 150, which will be described later, and can be expanded or reduced by a preset magnification. Expansion or reduction of magnification is adjusted according to the distance on the optical path between the first lens 130 and the Fresnel lens 150.

The surface of the first lens 130 closest to the mirror 120a in the direction in which light is incident may have a radius of curvature within a preset range based on -14.3mm and a thickness within a preset range based on 5.00mm. , the surface located furthest from the mirror 120a may have a radius of curvature within a preset range based on 64.9 mm and a thickness within a preset range based on 6.00 mm. Here, the preset range for the radius of curvature may be ±10mm, and the preset range for the thickness may be ±5mm. If the radius of curvature and thickness are outside the range of the above-mentioned values, a problem arises in which the clarity and wide angle of the output augmented reality image cannot reach the target values. Accordingly, the above-described surfaces of the first lens 130 must satisfy the above-described conditions.

The MEMS mirror 140 is disposed at a position where light is focused by the first lens 130, adjusts the direction of light and reflects it to the mirror 120b. The MEMS mirror 140 is disposed between the first lens 130 and the mirror 120b on the optical path and reflects the light focused by the first lens 130 to the mirror 120b. The MEMS mirror 140 is implemented with an area equal to the beam width that the augmented reality image to be output should have, and adjusts the beam width along with the direction of light. Here, the width of the augmented reality image adjusted by the MEMS mirror 140 may be tens to hundreds of μm. In this way, when the beam width of the light to be irradiated is reduced, the clarity of the image to be finally output can be significantly improved. This is shown in Figure 3.

FIGS. 3A and 3C are diagrams showing images output from a conventional AR glass display device, and FIGS. 3B and 3D are diagrams showing images output from an AR glass display device according to an embodiment of the present invention.

As shown in FIGS. 3A and 3C, when an augmented reality image with a beam width of several millimeters to tens of millimeters is output from a conventional AR glass display device, it can be seen that the clarity is relatively poor.

On the other hand, as shown in FIGS. 3B and 3D, when an augmented reality image with a beam width of tens to hundreds of μm is output from the AR glass display device according to an embodiment of the present invention, clarity is relatively improved. You can check it.

Referring again to FIG. 1, the MEMS mirror 140 can rotate for each axis in three dimensions based on its center. Since the MEMS mirror 140 can be rotated on each axis, the path of light incident on it can be actively adjusted. The MEMS mirror 140 does not just reflect light along a fixed path, but can actively adjust the path of reflected light.

The mirrors 120b and 120c reflect the light reflected from the MEMS mirror 140 to the Fresnel lens 150. The number of mirrors placed can be adjusted according to the size of the entire AR glass display device.

The Fresnel lens 150 adjusts the path of light incident on it to parallel light. Passing through the first lens 130, the augmented reality image is focused near the MEMS mirror 140 and then begins to disperse again. The dispersed augmented reality image passes through the Fresnel lens 150 and is adjusted into parallel light. Accordingly, the width (area) of the augmented reality image or the viewing angle of the image to be incident on the wearer's pupil 180 will be adjusted according to the distance from the MEMS mirror 140 to the Fresnel lens 150 on the light (augmented reality image) path. You can. However, the Fresnel lens 150 does not necessarily need to be disposed, and may be replaced with any device that can adjust the path of light incident thereto into parallel light.

The Fresnel lens 150 may have a radius of curvature within a preset range based on -15.8mm and a thickness within a preset range based on -1.50mm.

The optical waveguide 160 reflects the light that has passed through the Fresnel lens 150 to the semi-transmissive concave mirror 170, and transmits the light that has passed through the semi-transmissive concave mirror 170 and the light external to the device to the pupil 180. The optical waveguide 160 transmits the light (augmented reality image) entering the inside by total reflection, but transmits the transmitted light to the semi-transparent concave mirror 170 on the axis where the wearer's pupil 180 faces the outside of the device. Alternatively, light reflected from the semi-transmissive concave mirror 170 or light incident on the device from the outside is transmitted through the pupil 180. Accordingly, the light that has passed through the Fresnel lens 150 travels to the semi-transmissive concave mirror 170 near the axis where the wearer's pupil 180 faces the outside of the device.

The semi-transmissive concave mirror 170 reflects light (augmented reality image) that enters it through the optical waveguide 160, and transmits light that enters it from the outside. The transflective concave mirror 170 reflects the augmented reality image incident on it to the pupil 180. At this time, since the semi-transmissive concave mirror 170 is implemented in the form of a concave mirror, when light enters it through the optical waveguide 160, the light may be dispersed and proceed. Accordingly, the light of the augmented reality image reflected from the self may have a significant viewing angle when entering the pupil 180. For example, the augmented reality image incident on the pupil 180 may have a viewing angle of approximately 80°. Meanwhile, since the semi-transmissive concave mirror 170 transmits light entering the pupil 180 from outside the device 100, the wearer can perceive the augmented reality image as augmented reality.

The semi-transmissive concave mirror 170 may have a radius of curvature within a preset range based on -50.0mm and a thickness within a preset range based on -9.00mm.

In this way, the beam width is adjusted using the MEMS mirror 140, the viewing angle is improved using the semi-transmissive concave mirror 170, and the first lens 130, the Fresnel lens 150 and the transflective concave mirror ( As 170 satisfies the above-mentioned conditions, the AR glass display device 100 can provide the wearer with an AR image with an ultra-wide angle while improving clarity.

In addition, it can be confirmed that the AR image provided by the AR glass display device 100 has a significantly reduced distortion rate as shown in FIGS. 8 and 9.

Figure 8 is a diagram measuring the distortion rate of an augmented reality image output from an AR glass display device according to an embodiment of the present invention, and Figure 9 is a diagram measuring the distortion rate of an augmented reality image output from an AR glass display device according to an embodiment of the present invention. This is a diagram measuring the distortion rate according to the viewing angle.

Referring to FIG. 8, it can be seen that the maximum distortion rate of the augmented reality image output from the AR glass display device 100 is 3.9184%.

In addition, referring to FIG. 9, among the total viewing angles (80°) of the augmented reality image output from the AR glass display device 100, the maximum distortion rate at 40°, which is within the viewing angle range actually perceived by the wearer, is -0.5589%. You can check what you have.

In this way, the AR glass display device 100 can provide a more realistic feeling to the wearer by outputting an augmented reality image with a reduced distortion rate.

Figure 2 is a diagram showing the configuration of an AR glass display device according to a second embodiment of the present invention.

Referring to FIG. 2, the AR glass display device 200 according to the second embodiment of the present invention includes a projector 210 instead of the projector 110 and a mirror 120d instead of the MEMS mirror 140, and the AR glass The remaining components of the display device 100 are all included in the same manner.

The projector 210 outputs an augmented reality image to the mirror 120a. However, the projector 210 is not only a light source (not shown) for outputting an augmented reality image, but also a micro lens array that is disposed in front of the light source (not shown) in the direction in which the light source radiates light and adjusts the line width of the irradiated light. (Micro Lens Array, not shown) is also included. The projector 210 can directly adjust the beam width to be output without adjusting the beam width by the MEMS mirror 140. The projector 210 outputs an augmented reality image with a width of tens to hundreds of micrometers.

Since the augmented reality image output in this way corresponds to a state in which the beam width has already been adjusted, the output light is transmitted without the need for the MEMS mirror 140 to be placed between the first lens 130 and the mirror 120b on the optical path. A mirror 120d that fully reflects the light is disposed.

Accordingly, the AR glass display device 200 can output an augmented reality image that is clear and has an ultra-wide angle without light loss.

Figure 4 is a diagram showing the configuration of an AR glass display device according to a third embodiment of the present invention.

Referring to FIG. 4, the AR glass display device 400 according to the third embodiment of the present invention includes an optical waveguide 410 instead of the optical waveguide 160 and two Fresnel lenses 150a and 150b, The remaining components of the AR glass display device 100 are all included in the same manner.

Like the Fresnel lens 150, the Fresnel lens 150a adjusts the light (augmented reality image) dispersed through the first lens 130 into parallel light.

The optical waveguide 410 receives the light (augmented reality image) that has passed through the Fresnel lens 150a and transmits it by total reflection inside, and the light that is transmitted by total reflection on the axis where the wearer's pupil 180 faces the outside of the device ( Augmented reality image) or light incident on the device from the outside proceeds to the pupil 180. The light (augmented reality image) incident on the optical waveguide 410 is transmitted through total reflection inside the optical waveguide 410, has a relatively large viewing angle, and proceeds to the pupil 180.

The Fresnel lens 150b focuses light passing through the optical waveguide 410 onto the wearer's pupil 180 on an axis where the wearer's pupil 180 faces the outside of the device. The Fresnel lens 150b is disposed at a position where light is irradiated from the optical waveguide 410 to the wearer's pupil, and directs light (augmented reality image) or light incident to the device 400 from the outside into the wearer's pupil (180). ) to focus.

Figure 5 is a diagram showing the configuration of an AR glass display device according to a fourth embodiment of the present invention.

Referring to FIG. 5, the AR glass display device 500 according to the fourth embodiment of the present invention includes a projector 210 instead of the projector 110 and a mirror 120d instead of the MEMS mirror 140, and the AR glass The remaining components of the display device 400 are all identical.

Accordingly, the AR glass display device 500 can also improve the clarity of the augmented reality image by adjusting the beam width using the projector 210 without including a separate MEMS mirror 140.

Figure 6 is a diagram showing the configuration of an AR glass display device according to a fifth embodiment of the present invention.

Referring to FIG. 6, the AR glass display device 600 according to the fifth embodiment of the present invention includes a projector 110, mirrors 120a, 120b, and 120c, a first lens 130, a MEMS mirror 140, It includes a Fresnel lens 150, a field lens unit 610, and a transflective mirror 620. Here, the projector 110, mirrors 120a, 120b, 120c, first lens 130, MEMS mirror 140, and Fresnel lens 150 perform the same operation as those in the AR glass display device 100. Detailed description is omitted below.

The field lens unit 610 focuses light reflected from the transflective mirror 620 and light incident on the device 600 from the outside onto the wearer's pupil 180. The field lens unit 610 includes a field lens 614 disposed on an axis where the wearer's pupil 180 faces the outside of the device, and a housing 618 that places and fixes the field lens inside.

The field lens 614 focuses the light (augmented reality image) reflected from the transflective mirror 620 by reflecting it in the direction of the pupil 180. Conversely, the field lens 614 focuses light incident on the device 600 from the outside onto the wearer's pupil 180. Since light (augmented reality image) with an ultra-wide viewing angle passes through the Fresnel lens 150 and enters the field lens 614, the light (augmented reality image) focused from the field lens 614 to the pupil 180 is also It can have an ultra-wide angle.

The housing 618 secures the field lens 614 by placing it on an axis along which the wearer's pupil 180 faces the outside of the device. Meanwhile, the housing 618 is made of a material capable of total reflection for light incident on it at a certain angle, so that the light (augmented reality image) passing through the Fresnel lens 150 is transmitted to the transflective mirror 620. Reflect it.

The semi-transmissive mirror 620 reflects the (pre-)reflected light (augmented reality image) from the housing 618 to the field lens 614, and transmits the light focused from the field lens 614 to the pupil 180. .

At this time, the first lens 130 and the Fresnel lens 150 have the same curvature and thickness as those of the AR glass display device 100, and the field lens 614 has the same curvature and thickness as the transflective concave mirror 170. It has the same curvature and thickness. Accordingly, the AR glass display device 600 can also output an augmented reality image with an ultra-wide angle and sufficient clarity, and at the same time output an augmented reality image with minimized image distortion.

Accordingly, the AR glass display device 700 can also improve the clarity of the augmented reality image by adjusting the beam width using the projector 210 without including a separate MEMS mirror 140.
