Detailed description of the invention
Fig. 1 is a kind of schematic diagram of high-precision air display system provided by the invention.
Specific embodiment
Preferred embodiment provided by the invention is illustrated with reference to the accompanying drawings.
Fig. 1 is a kind of preferred embodiment of high-precision air display system provided by the invention.As shown in Figure 1, the height
Precision air display system includes the pictcure generator 10 for emitting linearly polarized photon, and the inclined upward of pictcure generator 10 is set
Have reflective inclined for being reflected the linearly polarized photon that pictcure generator 10 launches with linear polarization angle
Light film 20, the polarization angle of linearly polarized photon that pictcure generator 10 issues hang down mutually with the polarization angle of reflecting type polarizing film 20
Directly；The side of reflecting type polarizing film 20 is equipped with for handling the linearly polarized photon reflected back by reflecting type polarizing film
It forms the wave plate 30 of round polarised light and makes converse be emitted back towards for carrying out reflex reflection to the round polarised light by wave plate 30
Light sequentially pass through wave plate and reflecting type polarizing film and in the Counter-reflection membrane 40 of reflecting type polarizing film other side focal imaging, value
It obtains it is noted that formation when by wave plate 30 of the converse round polarised light being emitted back towards is identical as 20 polarization angle of reflecting type polarizing film
Linearly polarized photon, launch the linearly polarized photon with linear polarization angle, reflecting type polarizing in pictcure generator 10 in this way
Pictcure generator 10 is issued the polarised light with linear polarization angle and reflexes to wave plate 30 by film 20, by wave plate 30 with wired
Property polarization angle linearly polarized photon polarization properties variation occurs, become round polarised light, round polarised light continues transmitting to inverse
At reflectance coating 40, due to the high-accuracy micro-prism structure of Counter-reflection membrane 40, converse by the high regression of round polarised light is emitted back towards original
Path, polarization properties occur when the converse round polarised light being emitted back towards again passes by wave plate to be become polarizing with reflecting type polarizing film
The identical linearly polarized photon of angle, and continue by original route to reflecting type polarizing film retroeflection, due to this time polarization properties with
Reflecting type polarizing film is equal, and wide amount passes through, and the focal position for finally converging to the reflecting type polarizing film other side is formed for viewing
Clearly picture is imaged in air to the high brightness and picture that person checks, imaging picture in this way is clear, institute before obtaining in visual experience
The visual experience not having.
The angle of described image generator 10 and the reflecting type polarizing film 20 is α, the reflecting type polarizing film with it is described
The angle of wave plate is β, and the angle of the wave plate and described image generator 10 is γ, and alpha+beta+γ is 180 °；As a kind of preferable

Light, the linear polarization angle of the reflecting type polarizing film 20 are 180 degree；The wave plate 30 is quarter-wave plate, described converse
Penetrating film 40 is high regression Counter-reflection membrane；As shown in Figure 1, selecting 10 conduct of pictcure generator for having 90 ° of linear polarization angles
Imaging source, pictcure generator 10 issue the linearly polarized photon for having 90 ° of polarization properties, when linear with 90 ° of polarization properties
Polarized light emission to 180 ° of linear polarization angles of band reflecting type polarizing film when, since polarization properties are orthogonal, with 90 ° polarization
The linearly polarized photon of attribute is largely reflexed at quarter-wave plate, and polarization properties occur by the light of quarter-wave plate
Variation, becomes 135 ° of round polarised light and continues to emit supreme regression Counter-reflection membrane, due to high regression Counter-reflection membrane
135 ° of the converse of the high regression of round polarised light is emitted back towards original route by high-accuracy micro-prism structure, at this point, 135 ° it is round partially
The light light that shakes occurs polarization properties again through quarter-wave plate and changes, and becomes 180 ° of linearly polarized photons, and continue by former road
Radial reflecting type polarizing film retroeflection, due to the polarization properties of 180 ° of linearly polarized photons at this time and the polarization category of reflection type polarizing film
Property is equal, and 180 ° of linearly polarized photons largely pass through, and finally converge to aerial focal position, the position and reflection type polarizing film
Apart from it is almost equal at the light source transmitting of pictcure generator at a distance from reflection type polarizing film, shown due to pictcure generator
For picture after above structure, people in range covering viewing angle is projected in tapered tapered diverging injection after converging to focal position
Binocular human eye, since binocular human eye or so eyeball captures the focal position from identical image generator respectively but does not share the same light
The light in path, binocular human eye see pictcure generator imaging from the focal position, achieve the effect that air-borne imagery.
It is worth noting that, quarter-wave plate be it is certain thickness linearly polarized light can be converted to circularly polarized light, or
Otherwise circularly polarized light is converted to a kind of anisotropic crystal microchip of linearly polarized light.When light normal incidence penetrates chip
When, direction of vibration and chip optical axis folder the angle θ (θ ≠ 0), incident light vibration resolve into perpendicular to optical axis (o vibration) with it is parallel
In two components of optical axis (e vibration), they correspond to the ordinary light (o light) and non-ordinary light (e light) in chip, the ordinary light in chip
(o light) and non-ordinary light (e light) are propagated in the same direction, and the phase difference between ordinary light (o light) and non-ordinary light (e light) is equal to pi/2
Or its odd-multiple, such chip are known as quarter-wave plate or quarter wave plate.
In the application, quarter-wave plate is fitted on Counter-reflection membrane, is integrated.Polarised light passes through quarter-wave
The polarization properties of piece, light are changed: linearly polarized photon passes through quarter-wave plate, is converted to round polarised light；Round polarization
Light passes through quarter-wave plate, is converted to line style polarised light；Polarization angle is every by once deflecting 45 degree simultaneously.
