Description
Technical field
The present embodiments relate to optics display technology field, more particularly, to a kind of air suspension display system.
Background technology
From black and white display to color monitor, from CRT monitor to quantum dot displays, from flat-panel screens to bore hole
3D display device.For a long time, people constantly study new display technology, and these display technologies have been successfully applied to each
Field, such as life ＆ amusement, display and demonstration, advertisement media, medical education, military commanding etc..It is empty in numerous display technologies
Among middle suspension display technology by image due to that can be presented on air, strong visual impact and also very also is brought for viewer
False sensory experience is so as to receive the concern of many researchers.The three of real-world object are broadly divided into from the image category to suspend out
The planar aerial for tieing up air imaging and dummy object is imaged.Real-world object is mainly placed in suspension display system by the former, is led to
It crosses to illuminate to real-world object and the aerial real-world object that suspends can be watched by the display system so as to fulfill observer.Afterwards
After the virtual image that person mainly shows the flat-panel screens such as LCD is by display system, realize in the plane to suspend in the air
Hold.The essence of suspension display system is can be into the optical system of real image, and the work report of researcher mainly may be used according to before
To be divided into five classes：
Concave mirror bonus point light microscopic：The optical texture is the scheme that such display system proposes earliest.It is to be illuminated true
The content that real object or LCD are shown is reflected into concave mirror by spectroscope, and light is made by the convergence of concave mirror
It is imaged with again by after spectroscope in its opposite side.At this point, observer can see the image of air suspension.In order to avoid
Ambient light influences visual experience, can add in circular polarizing disk in systems to inhibit the influence of environment veiling glare.The advantages of this scheme
It is simple in structure, cost can be greatly reduced after the spherical mirror of application resin material.Shortcoming is：The picture size of suspension
It is small, viewing visual angle is small and anamorphose is serious.
Coaxial configuration：The problem of for solution 1, researcher proposes axis reflector structure, the class formation
Mainly it is made of, and mirror center above is provided with the thang-kng of certain size the axis upper reflector of upper and lower two faces
Aperture.Real-world object is positioned over the inside of two speculums, and the light that object is sent out is after the reflection of upper and lower two speculums
It is projected at the clear aperature of top speculum, so as to be imaged in the air.Advantage：Observer can in the range of 360 degree ring
Depending on the skyborne object picture that suspends；Easy assembling simple in structure.Shortcoming：Due to there is thang-kng aperture above, observer is at it
It can not be watched in the range of the certain angle of top；Display small-sized image is only applicable to, if display large-size images, display system
The size of system very huge can reduce practicability again so as to increase cost.
Off axis reflector structure：For further improvement, researcher has also been proposed off axis reflector structure.Display source it is interior
Hold by being imaged in the air after speculum multiple reflections that are off-axis and rotating by a certain angle.Advantage：Pass through the off-axis solution of speculum
The problem of coaxial configuration of having determined can not be observed above；Viewing visual angle is big, display resolution is high.Shortcoming：As a result of off-axis
Mode, therefore the face type of speculum must be aspherical face type so as to eliminate the decectration aberration because introducing off axis, this increase
Technology difficulty and cost；The mutual distance of speculum and respective rotation angle bring great difficulty for assembling；It is unsuitable
Show the suspended images of large-size.
Retroreflective structure adds beam splitter：In order to realize large-size suspended images, researcher is proposed based on converse
Penetrate structure and the air suspension display system of beam splitter.The structure mainly be made of hollow or solid sphere lens and
The surface of lower semisphere is coated with reflectance coating.The structure can realize the effect that reflection light is mutually parallel with incident ray and direction is opposite
Fruit.The light that display source is sent out is incident on retroreflective structure through beam splitter, will be along entering by the reflection light of retroreflective structure
The opposite direction for penetrating light is imaged again by beam splitter so as to be converged in its opposite side.Advantage：It can realize large-size
It suspends and shows image；Processing technology is ripe, at low cost；Viewing visual angle is big.Shortcoming；Since the serious aberration of sphere lens results in
Suspended images are very fuzzy, significantly impact the display effect of suspended images.
Double layer planar lens array：The program is made of upper and lower two layers of planar mirror array and the plane mirror unit between two layers
It is mutually perpendicular to.The light that display source is sent out is converged in opposite side after the reflection of the planar mirror array and is imaged.Advantage：Due to being
Therefore there is no aberrations for system for plane mirror catoptric imaging, can realize a undistorted, high-definition suspended images.Shortcoming：
Convergence imaging after primary event should respectively be occurred on upper and lower two layers of planar mirror array by theoretically showing each light in source.It is practical
In may multiple reflections occur before two layers speculum again, this causes observer also can be simultaneously while suspended images are seen
Observe ghost；The interval of mirror unit determines that the display frequency of system and resolution ratio are relatively low；Effective viewing visual angle is small；
The efficiency of light energy utilization is low；Cost of manufacture is high.
In conclusion there are observation visual angle is small, imaging size is small and air suspension is shown for existing air suspension display system
The problems such as showing fogging image.
