Specific embodiment
The content of present invention is described in detail with specific embodiment with reference to the accompanying drawings of the specification:
Embodiment 1:
The high resolution A R glasses light for one kind provided by the invention as shown in Figs 1-4, it is characterised in that: including mirror holder
1 and two groups of AR optical elements being set on mirror holder 1, every group of AR optical element includes being set to mirror holder along light incident direction
Object lens 2, micro display device 3, eyepiece 4, inversion prism 5 on 1, the object lens 2 and eyepiece 4 are using same shape identical focal length
Positive lens, the plane of incidence and exit facet of the inversion prism 5 are perpendicular with optical axis, and the micro display device 3 is located at eyepiece 4 one
Within the optical length of times focal length, the optical length and eyepiece 4 of the focal plane of the object lens 2 to object lens 2 arrive the focal plane of object lens 2
Optical length it is equal.In the present embodiment, the object lens 2 and eyepiece 4 use biconvex lens, naturally it is also possible to saturating using plano-convex
Mirror.
The micro display device 3 includes microprocessor and micro display device, and microprocessor is connected with micro display device
State is shown to control following four of the virtual image on micro display device:
A. the micro display device be can display microprocessor export image and penetrated in front of micro display device sees again
The semi-transparent semi-reflecting display of outdoor scene makes one the superposition for arriving virtual image and real scene image soon；
B. the micro display device is that can be presented two kinds in only display microprocessor output image and fully transparent no image
The time-division display alternately switched between state, makes human eye that virtual image and outdoor scene be respectively seen in very short time slot, by
In the delay of human eye sense organ, such human eye just sees the superposition of seemingly virtual image and outdoor scene；
C. the micro display device is transparent display, the portion of display microprocessor output image in the micro display device
Point be it is opaque, micro display device rest part be it is transparent, through transparent part it is seen that outdoor scene, makes one to arrive soon
The superposition of virtual image and real scene image；
D. the micro display device is transparent display, the portion of display microprocessor output image in the micro display device
Point be it is translucent, micro display device rest part be it is transparent, can through not display image portion point and display image portion point
To see outdoor scene, the superposition for arriving virtual image and real scene image soon is made one.
As shown in Figure 3-4, the inversion prism 5 uses other Chinese inversion prism, and the inversion prism 5 is by one and half five jiaos of ribs
Mirror 51 and a roof prism 52 form.Wherein the angle a in half pentagonal prism 51 is 45 degree, and angle b is 112.5 degree, ridge
Angle c in prism 52 is 45 degree, and the focal range of the object lens 2 and eyepiece 4 is 6mm~50mm, different focus designs, thoroughly
The amplification factor of virtual digit information, the size of image distance, field angle, entire glasses are all different in obvious display screen.Simultaneously
The selection of lens material also will affect design, and the refractive index of the object lens 2 and eyepiece 4 is 1.5~1.8.The material of inversion prism
Refractive index is very big on the influence of the field angle of glasses, and the refractive index of the inversion prism 5 is 1.5~2.0, the bigger material of refractive index
The field angle of the achievable glasses of the inversion prism done is bigger.
It is with the focal length of lens below for 26mm, material selection one parameter computational chart of acrylic (PMMA):
As shown in Figure 1, the mirror holder 1 include 11, two legs of spectacles 12 being articulated on mirror holder ontology 11 of mirror holder ontology with
And two lens barrels 13 being fixedly installed on mirror holder ontology 11, every group of AR optical element are installed in corresponding lens barrel 13.Institute
Stating mirror holder 1 further includes the preceding mirror cover 14 for being fixedly installed on 11 front end face of mirror holder ontology and rising to the front end of lens barrel 13 position-limiting action
And it is fixedly installed on 11 rear end face of mirror holder ontology and rises to the rear end of lens barrel 13 the rear mirror cover 15 of position-limiting action.
In the present embodiment, for the optical system of AR glasses by object lens, micro display device, eyepiece, inversion prism this four is main
Part forms.Positive lens is to play amplification to the image of display screen as eyepiece, and micro display device is located at the focal length f of positive lens
Within, such human eye is through this positive lens it is seen that the virtual image amplified on micro display device.If in micro display device
Before without other optical components, then penetrating the actual environment outdoor scene of micro display device generally all in the focal length of twice of positive lens
Other than (2f), then penetrating this positive lens, human eye is the inverted image that can only see diminution.That is reality scene be it is untrue or
It does not see.Object lens are one and eyepiece parfocal, identical lens in the present embodiment, and the focus of two lens is overlapped, shape
At a symmetric optical system, by this optical system, human eye can see an inverted 1:1 reality scene therefore must
An inversion prism group, the reality scene for the handstand that inversion prism group generates two lens must be added between human eye and eyepiece
It is inverted again so that human eye sees normal reality scene.However, after eyepiece is to the amplification of transparent display screen virtual information,
Due to the addition of inversion prism, this virtual information can be also squeezed once.Therefore, it when transparent display screen shows and designs, to allow
Lenticular display screen shows inverted information.Simultaneously because optical path is reversible, use can also be turned around, i.e. eyepiece adds inverted image rib
Mirror end is towards object (outdoor scene), and objective end towards eyes.
Embodiment 2:
As seen in figs. 5-6, embodiment 2 the difference from embodiment 1 is that: it is saturating that the object lens 2 and eyepiece 4 are all made of Fresnel
Mirror, the eyepiece 4 are fixedly arranged between half pentagonal prism 51 and two binding faces of roof prism 52.In this embodiment, object lens 2
Fresnel Lenses is used with eyepiece 4, the thickness of lens is reduced, keeps AR glasses lighter, and eyepiece 2 is fixedly arranged on half five jiaos of ribs
Between mirror 51 and two binding faces of roof prism 52, half pentagonal prism 51 has shared the light path that eyepiece 2 arrives micro display device 3,
The distance between inversion prism 5 and micro display device 3 can further decrease, and total can design smaller.
Above-mentioned specific embodiment is only explained in detail technical solution of the present invention, the present invention not only only office
It is limited to above-described embodiment, all any improvement or replacement according to the principle of the invention should all be within protection scope of the present invention.
