The infrared external reflection diffraction element 70 is arranged at the guide-lighting substrate 13 close to the one side of human eye or separate human eye.Institute
Spherical wave can be converted to by plane wave by stating infrared external reflection diffraction element 70.The infrared external reflection diffraction element 70 can be one layer of tool
There is the transparent mantle of infrared external reflection diffraction pattern characteristic, the infrared external reflection diffraction element 70 is attached at the guide-lighting substrate 13.
The infrared external reflection diffraction element 70 can also be the element for being etched with infrared external reflection diffraction pattern on the transparent substrate, described red
External reflectance diffraction element 70 with the guide-lighting substrate 13 there is the air gap or the infrared external reflection diffraction element 70 to be led with described
Light substrate 13 is glued together.The reflection emergent light axis of the infrared external reflection diffraction element 70 and the infrared photography module 50
Optical axis is substantial parallel or coaxial.Wherein, it is substantial parallel or coaxial refer to close to parallel or coaxial.For the infrared external reflection
The reflection emergent light axis and the optical axis of the infrared photography module 50 of diffraction element 70 have the inclined of low-angle in tolerance interval
Difference and substantial parallel or coaxial.
When the infrared external reflection diffraction element 70 is arranged at the guide-lighting one side of the substrate 13 away from human eye, which shows
The light path schematic diagram that the virtual image of device 1 is shown is as shown in Figure 2.The leaded light substrate 13 includes inclined cut S131, the
One working face S133 and the second working face S135.The image light of 11 output of display output light group enters guide-lighting substrate
13, the first working face S133 is totally reflected to by the inclined cut S131 of guide-lighting substrate 13, the first working face S133 is to entering
The light beam penetrated is totally reflected to the second working face S135 again.And so on, the light beam of display output light group 11 passes through in leaded light
Multiple reflections between the first working face S133 and the second working face S135 of substrate 13 complete the transmission of light beam.Light beam passes
It is defeated to first tilt coupling surface 151 when, a part of light beam reflected after through after the second working face of guide-lighting substrate 13 to human eye
Direction is propagated, and another part light beam continues across first work of 151 onwards transmission of the first inclination coupling surface to guide-lighting substrate 13
Plane S133, the beam Propagation after being totally reflected by the first working face S133 tilt coupling surface 153 to second.Second is transferred to incline
The light beam part in oblique 153 face of coupling surface is propagated after the second working face of guide-lighting substrate 13 is passed through after being reflected to human eye direction,
Another part continues to transmit through the second inclination coupling surface 153.By this method, light beam tilts coupling surface 151, the by first successively
Two inclination coupling surfaces the 153, the 3rd are tilted after coupling surface the 155, the 4th tilts the reflection of 157 part of coupling surface and formed virtually into human eye
Image, for the virtual display of the artificial additional information to real world.Also, the nearly eye display device 1 also achieves
Light beam exports the extension of bore, increases exit pupil diameter.
Real world light is direct by the infrared external reflection diffraction element 70, guide-lighting substrate 13 and inclination coupling surface
It is transmitted into human eye.
As shown in figure 3, when the nearly eye display device 1 carries out human eye virtual image forming, infrared launcher 30 emits infrared
Light covers human eye scope, after human eye reflection or the infrared light scattered pass through guide-lighting substrate 13 and tilt coupling surface, by described red
The human eye virtual image formed after 70 reflection diffraction of external reflectance diffraction element is obtained by the infrared photography module 50.Due to described infrared
The reflection emergent light axis PK and optical axis OG of the infrared photography module 50 of reflection diffraction element 70 is substantial parallel or coaxial, because
This infrared photography module 50 can look straight to human eye imaging.The physical distance L1+L2 of human eye to infrared photography module 50 is very short, leads to
Often less than 100mm.And the nearest operating distance of infrared photography module 50 is typically much deeper than this value, usually between 300mm~3m.
Therefore, if infrared photography module 50 is directly imaged the infrared ray of human eye reflection, clearly human eye picture cannot be obtained.For
It solves the above problems, the nearly eye display device 1 that the utility model embodiment provides includes plane wave being converted to spherical wave
Infrared external reflection diffraction element 70.Infrared external reflection diffraction element 70 can form the human eye virtual image at infrared photography module 50L,
Infrared photography module 50 to human eye virtual image forming infrared photography module 50 receiving plane.Wherein, L can be more than 300nm, even
Reach 5m, then L falls in the range of the operating distance of infrared photography module 50, meets the distance of 50 blur-free imaging of infrared photography module
It is required that.Clearly as the imaging effect of infrared external reflection diffraction element 70 increases human eye to infrared photography module 50 indirectly
Equivalent Physical distance so that infrared photography module 50 can obtain the clear image of looking straight of human eye.Under normal conditions, it is raising people
The transmitance of the infrared light of eye reflex can also be to guide-lighting substrate 13 and inclination coupling surface plating infrared anti-reflection film.
In the prior art, infrared photography module 50 is directed towards human eye, and directly the infrared ray of human eye reflection is imaged.For
Infrared photography module 50 is avoided to cause partially or fully to block to the user visual field, infrared photography module 50 usually requires to be placed on
The periphery of the viewing area of nearly eye display device 1, the optical axis and human eye optical axis for then causing infrared photography module 50 have wide-angle
Deviation, it is impossible to obtain the image of looking straight of human eye.Also, physical distance of the human eye away from infrared photography module 50 is generally less than
Less than the nearest operating distance (between 300mm~3m) of infrared photography module 50, it is clear to be unsatisfactory for infrared photography module 50 by 100mm
The required distance of clear imaging.
Therefore, the nearly eye display device 1 that the utility model embodiment provides is obtained with clearly without face human eye
It looks straight image, does not disturb reception of the user to real world light, verified available for eye tracking, iris recognition identification
Deng.Wherein, image of looking straight refers to be equivalent to the eye image of the shooting angle shooting of face human eye.
When the infrared external reflection diffraction element 70 is arranged at the guide-lighting substrate 13 close to the one side of human eye, which shows
The structure of device 1 is as shown in Figure 4.The light path schematic diagram that the nearly eye display device 1 carries out human eye virtual image forming is as shown in Figure 5.It is red
The infrared light of the infrared light covering human eye scope that outer emitter 30 emits, human eye reflection or scattering is spread out by the infrared external reflection
The human eye virtual image formed after 70 reflection diffraction of element is penetrated to be obtained by the infrared photography module 50.By infrared external reflection diffraction element 70
The guide-lighting substrate 13 is arranged at close to the one side of human eye so that human eye reflects or the infrared light of scattering is directly by described infrared
The human eye virtual image formed after 70 reflection diffraction of reflection diffraction element is obtained again by the infrared photography module 50, avoids by leaded light
The transmitance of the infrared light of human eye reflection or scattering reduces caused by substrate 13 and inclination coupling surface and infrared stray light is to human eye
The influence of image taking, so as to which infrared photography module 50 can obtain clearer eye image.
