As shown in Figures 1 to 4, the utility model provides a kind of 3D line holographic projections equipment with peep-proof function, including complete
Cease pyramid 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, and the tower top 2 of the holography pyramid 1 is towards support frame 5, the holography pyramid 1
Side be mirrorlette 3, the mirrorlette 3 be used for receive film source screen 7a/7b/7c/7d projection image；It is described
Film 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 utility model, film source screen 7a/7b/7c/7d to
Holographic 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 complete in viewing
It cannot see that the image source on film source screen 7a/7b/7c/7d, therefore, the principle of line holographic projections when ceasing the image on pyramid 1
It is not easy to be 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 utility model, received using holographic pyramid 1
The image of film source screen 7a/7b/7c/7d projection, holographic pyramid 1 are zero mature in the prior art applied to line holographic projections
Component, the holographic pyramid 1 generally four sides cone made of the transparent materials such as glass, it is described holography pyramid 1 include tower top 2,
The mirrorlette 3 of tower bottom plane 4 and its side, the side of holographic pyramid 1 is mirrorlette 3, described pyramidal
Each perspective plane congruence.The sight of spectators can penetrate on one side it from any, and by surface reflection principle, spectators can be in cone space
See the image and figure of free floating.Optical signal is reflected on the special prism in this cone by four sides video imaging, is converged
Collect the stereopsis for being formed afterwards together and there is real dimensions space.It can use the coated glass production holographic pyramid 1.
In a kind of 3D line holographic projections equipment with peep-proof function of the utility model, due in film source screen 7a/7b/
Peep-proof film 8 is provided on 7c/7d, so spectators can't see on film source screen 7a/7b/7c/7d from the side of line holographic projections equipment
Presentation content, peep-proof film 8 use ultra tiny shutter optical technology so that the visual range of observer be and peep-proof film 8
The angled cone space range of normal, except visual range, observer can only see pitch-dark picture.Therefore, please join
Fig. 1 to Fig. 4 is examined, α is 8 visible angle of peep-proof film, and in the α angular range around 8 normal of peep-proof film, observer can see piece
Content on the screen 7a/7b/7c/7d of source, θ be peep-proof film 8 can not angle, the θ angular range around 8 normal of peep-proof film
Interior, observer can't see the content on film source screen 7a/7b/7c/7d.And spectators are usually the side court from holographic pyramid 1
Projection image is watched on mirrorlette 3, therefore, the visual angle of spectators is seen in the θ angular range around 8 normal of peep-proof film
Crowd can not see the presentation content on film source screen 7a/7b/7c/7d.Generally, the peep-proof film 8 with a thickness of 0.1~
0.5mm.Preferably, the support frame 5 has the mounting plane 6 for being laid with film source screen 7a/7b/7c/7d, the installation
