Convenient for being illustrated for narration, rather than to limit the scope of the invention, relativeness is altered or modified, in no essence
It changes under technology contents, when being also considered as the enforceable scope of the present invention.
As shown in Figures 1 to 4, the present invention provides a kind of 3D line holographic projections equipment with peep-proof function, including holographic gold
Word tower 1, support frame 5 and the film source screen 7a/7b/7c/7d being set on support frame 5；The film source screen 7a/7b/
7c/7d is layed on support frame 5, the tower top 2 of the holography pyramid 1 towards support frame 5, the holography pyramid 1
Side is mirrorlette 3, and the mirrorlette 3 is used to receive the image of film source screen 7a/7b/7c/7d projections；Described
Source screen 7a/7b/7c/7d is equipped with peep-proof film 8.
In a kind of 3D line holographic projections equipment with peep-proof function of the present invention, film source screen 7a/7b/7c/7d is to holography
1 upslide projection picture of pyramid, due to being equipped with peep-proof film 8 on film source screen 7a/7b/7c/7d, so spectators are in the holographic gold of viewing
It cannot see that the image source on film source screen 7a/7b/7c/7d when image on word tower 1, therefore, the principle of line holographic projections is not easy
It is cracked by spectators, mystique, the technology sense of hologram device are very strong.
In order to enable peep-proof effect is more preferable, as a preferred embodiment, at the surface frosted of the peep-proof film 8
Reason, in this way, hologram would not form image on peep-proof film 8 and be easily seen.
In a kind of 3D line holographic projections equipment with peep-proof function of the present invention, film source is received using holographic pyramid 1
The image of screen 7a/7b/7c/7d projections, holographic pyramid 1 are zero applied to line holographic projections of maturation in the prior art
Part, the generally four sides cone made of the transparent materials such as glass of holographic pyramid 1, the holography pyramid 1 includes tower top 2, tower
The side of the mirrorlette 3 of baseplane 4 and its side, holographic pyramid 1 is mirrorlette 3, described pyramidal each
Perspective plane congruence.The sight of spectators can penetrate it on one side from any, and by surface reflection principle, spectators can be in cone space
To the image and figure of free floating.Optical signal is reflected on the special prism in this cone by four sides video imaging, is collected
To together afterwards formed with real dimensions space stereopsis.Coated glass can be utilized to make the holographic pyramid 1.
In a kind of 3D line holographic projections equipment with peep-proof function of the present invention, due in film source screen 7a/7b/7c/
Peep-proof film 8 is provided on 7d, so spectators can't see the shadow on film source screen 7a/7b/7c/7d from the side of line holographic projections equipment
As content, peep-proof film 8 uses ultra tiny shutter optical technology so that the visual range of observer is and 8 normal of peep-proof film
Angled cone space range, except visual range, observer can only see pitch-dark picture.Therefore, it please refers to Fig.1
To Fig. 4, α is 8 visible angle of peep-proof film, and in the α angular ranges around 8 normal of peep-proof film, observer can see film source screen
Curtain 7a/7b/7c/7d on content, θ be peep-proof film 8 can not angle, in the θ angular ranges around 8 normal of peep-proof film,
Observer can't see the content on film source screen 7a/7b/7c/7d.And spectators are usually from the side of holographic pyramid 1 towards projection
Projection image is watched on receiving plane 3, therefore, the visual angle of spectators is in the θ angular ranges around 8 normal of peep-proof film, Guan Zhongwu
Method sees the presentation content on film source screen 7a/7b/7c/7d.Usually, the thickness of the peep-proof film 8 is 0.1~0.5mm.It is excellent
Selection of land, the support frame 5 have a mounting plane 6 for being laid with film source screen 7a/7b/7c/7d, the mounting plane 6 with
The bottom of tower plane 4 of holographic pyramid 1 is parallel.
Hereinafter, our specific implementation modes through the invention are explained technical scheme of the present invention.
The first specific implementation mode：
As shown in Figure 1, the tower top 2 of holographic pyramid 1 is downward, upward, film source screen 7a is corresponding to the tower top 2 for bottom of tower
The part of mounting plane 6 vacate, i.e., the regional area below the bottom of tower of holographic pyramid 1 does not have film source screen 7a.Film source screen
The upper surface of curtain 7a has peep-proof film 8, can use peep-proof film 8 and be adhesive on the upper surface of film source screen 7a.The thickness of peep-proof film 8
Degree is 0.1~0.5mm, 8 vertical transmitance >=70% of peep-proof film can have 70% or more on light vertical irradiation to peep-proof film 8
Light penetrate peep-proof film 8, the visible angle α of peep-proof film 8 is 10 °~45 °, and not visible angle, θ is 45 °~80 °, peep-proof film 8
Back side cloth glue is covered on film source screen 7a.The front of peep-proof film 8 is handled through frosted, prevents hologram shape on peep-proof film 8
At image.Film source screen 7a images are projected through after peep-proof film 8 to the mirrorlette 3 of 1 side of holographic pyramid, are formed
Hologram, since film source screen 7a is equipped with peep-proof film 8, so spectators can be prevented to be immediately seen piece from hologram device side
Image on the screen 7a of source.
Second of specific implementation mode：
As shown in Fig. 2, the film source screen 7b in the 3D line holographic projections equipment shown in Fig. 2 with peep-proof function is paved with support
Entire mounting plane 6 in framework 5, peep-proof film 8 are also paved with the entire upper surface of film source screen 7b.The tower top 2 of holographic pyramid 1
The thickness of face peep-proof film 8, peep-proof film 8 is 0.1mm, and the vertical transmitance of peep-proof film 8 reaches 85%, the angle of visibility of peep-proof film 8
It is 20 ° to spend α, and not visible angle, θ is 70 °.
The third specific implementation mode：
As shown in figure 3, in the present embodiment, the tower top 2 of the holography pyramid 1 upward, bottom of tower downward, holographic pyramid 1
It is placed on supporting table 9,6 region of mounting plane of 2 faces of tower top of holographic pyramid 1 is vacated, and film source screen 7c is not set
It sets in the region vacated.8 thickness of peep-proof film is 0.2mm, 8 vertical transmitance 80% of peep-proof film, the visible angle α of peep-proof film 8
It it is 25 °, the not visible angle, θ of peep-proof film 8 is 65 °.
4th kind of specific implementation mode：
As shown in figure 4, in the present embodiment, monoblock film source screen 7c is paved with the mounting plane 6 of support frame 5, by pre- cloth glue
Peep-proof film 8 be covered in the surface of film source screen 7c, holographic pyramid 1 is placed in supporting table 9, and the tower top 2 of holographic pyramid 1 is just
To peep-proof film 8.The thickness of peep-proof film 8 is 0.3mm, and the visible angle α of 8 vertical transmitance 75% of peep-proof film, peep-proof film 8 is 30 °,
The not visible angle, θ of peep-proof film 8 is 60 °.
Technical solution based on above-described embodiment, a kind of 3D line holographic projections equipment with peep-proof function of the invention can
Prevent spectators from seeing the image source on film source screen in the image on viewing holography pyramid 1, moreover, the increase of peep-proof film 8
Hologram display effect is not influenced, and therefore, the principle of line holographic projections is not easy to be cracked by spectators, the mystique of hologram device, section
Skill sense is very strong.
In conclusion the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology can all carry out modifications and changes to above-described embodiment without violating the spirit and scope of the present invention.Cause
