Embodiment
To be fully understood by the purpose of this utility model, feature and effect, now by following specific embodiments, and coordinate attached
Figure, is described in detail as follows to the utility model：
Scattered as shown in figure 1, head-wearing display device of the present utility model includes micro- projecting cell 1, Amici prism 2, first
Plate 5, the second scatter plate 6, the first spectroscope 7 and the second spectroscope 8.Image optical information to be shown is sent out by micro- projecting cell 1
Go out, the first light beam a and the second light beam b are divided into by Amici prism 2, split screen display available is realized.First light beam a passes through the first scattering
Plate 5 is incident to the first spectroscope 7, and the first eyeball 3 of people is entered after being reflected by the first spectroscope 7.Second light beam b passes through
Two scatter plates 6 are incident to the second spectroscope 8, and the second eyeball 4 of people is entered after being reflected by the second spectroscope 8.
In the present embodiment, micro- projecting cell 1 uses micro projector, its have higher brightness, can after split screen according to
So ensure that enough brightness supplies eye-observation.
Amici prism 2 is using common 1：1 Amici prism, the main cross section of prism is quadrangle, and it includes entering image light
The first side penetrated, the second side for being connected to first side two ends and the 4th side and connection second side and the
3rd side of four sides.There is spectro-film, the spectro-film is placed perpendicular to the plane of main cross section in the Amici prism 2
On.
The image optical information light point that micro- projecting cell 1 is sent is incident to after spectro-film by first side to be divided into two, one
Divide and form the first light beam a via the 3rd side outgoing directly through spectro-film.Another part is reflected via second by spectro-film
Side outgoing and form the second light beam b.The energy ratio of two parts divided beams is 1:1, it can also be needed to be set to it according to system
His ratio.
Further, as shown in figure 3, quadrangle Amici prism can be intercepted as six sides in the case where not influenceing light to propagate
Shape Amici prism, i.e., the angle formed first side and second side is cut out, and the 3rd side is formed with the 4th side
Angle cut out.So that by between the 5th side connection, the 3rd side and the 4th side between first side and second side
Connected by the 6th side.Volume is further reduced with this, mitigates the weight of head-wearing display device.
First scatter plate 5 and the second scatter plate 6 are set up in parallel, and correspond to the first eyeball 3 and the second eyeball 4 of people respectively.
First scatter plate 5 and the second scatter plate 6 can be projection-type or reflective.The the first light beam a projected by Amici prism 2
First spectroscope 7 is incident to by the first scatter plate 5, the second light beam b is incident to the second spectroscope 8 by the second scatter plate 6.Enter
One step, as shown in Fig. 2 the first scatter plate 5 and the second scatter plate 6 are the high reflective aluminium sheet with scattering film, can be first
Occurs diffusing reflection during light beam a and the second light beam b irradiations.The focal length of micro- projecting cell 1 is adjusted, the first scatter plate 5 and second is dissipated
Penetrate on plate 6 into clearly as.
First spectroscope 7 and the second spectroscope 8 are disposed in parallel in the first scatter plate 5 and the outgoing beam of the second scatter plate 6
Side, and the first scatter plate 5 and the second scatter plate 6 are corresponded to respectively.First spectroscope 7 and the second spectroscope 8 can for split or
Disjunctor, the side of its incident beam has anti-reflection film, the side of outgoing beam has spectro-film, or incident beam side tool
The side for having spectro-film, outgoing beam has anti-reflection film.Depending on the light splitting rate of spectro-film is by ambient light, the ambient light high time-division
The reflectivity of light film is high, and the reflectivity of spectro-film is low when ambient light is low, and the reflectivity is between 30%~70%.Further
The material of ground, the first spectroscope 7 and the second spectroscope 8 is polymethyl methacrylate or makrolon.First light beam a passes through
One scatter plate 5 is incident to the first spectroscope 7, and enters the first eyeball 3 of people after being reflected by the first spectroscope 7；Second light beam b leads to
Cross the second scatter plate 6 and be incident to the second spectroscope 8, and enter the second eyeball 4 of people after being reflected by the second spectroscope 8.This practicality
New presented image has the uniformity of height in terms of the time and as matter.
Further, due to the spectroscope 8 of the first spectroscope 7 and second of the present utility model be plane, sphere, it is aspherical or
Free form surface one kind therein, can make presented image produce certain distortion, the distortion is difficult to be carried out by optical system
Correction.Therefore, as shown in figure 4, micro- projecting cell 1 of the present utility model can do predistortion processing in projecting beam, micro- throwing is made
Shadow unit 1 on the first scatter plate 5 and the second scatter plate 6 imaging respectively as shown in the first image 14, the second image 15.In advance
Distortion processing after the first light beam a and the second light beam b reach human eye when, its into image abnormal vanishing, reached as
The distortion effect of image zero shown in display image 16.
It is to be understood that the utility model is described by some embodiments, those skilled in the art are not taking off
In the case of from spirit and scope of the present utility model, various changes can be carried out to these features and embodiment or equivalent are replaced
Change.In addition, under teaching of the present utility model, these features and embodiment can be modified with adapt to particular situation and
Material is without departing from spirit and scope of the present utility model.Therefore, the utility model is not by specific implementation disclosed herein
The limitation of example, the embodiment fallen with the range of claims hereof belongs to protection domain of the present utility model.
