Embodiment
Fig. 1 is the structural schematic diagram of reflex reflection stereo projection display apparatus 010 provided in this embodiment.X coordinate table in figure
Show the horizontal direction in space, the vertical direction in y coordinate representation space, z indicates the direction vertical with x-y plane.It please refers to
Fig. 1, the present embodiment provides a kind of reflex reflection stereo projection display apparatus 010 comprising the projection that four projectors 300 are constituted
Machine array, Lenticular screen 200 and Counter-reflection membrane 100.Lenticular screen 200 and 100 front and back of Counter-reflection membrane are successively close to place.
Lenticular screen 200 is placed in front of Counter-reflection membrane 100, is arranged in vertical direction by multiple cylindrical lens.Counter-reflection membrane
100 use cubic structure, and periodic structure can will be entered by constituting in the square plane of reflection of 90 degree of orthogonally located three
The light being mapped on the Counter-reflection membrane is reflected by former incident direction.Projector array is in different level position by more
Projector 300 forms, and can project anaglyph at 100 position of the Lenticular screen 200 and the Counter-reflection membrane.Array
In each projector 300 project a corresponding anaglyph respectively.
Reflex reflection stereo projection display apparatus 010 provided in this embodiment is further described below.
The light that any projector 300 is issued in projector array is incident on reflex reflection through Lenticular screen 200 first
Film 100.Referring to figure 2., Counter-reflection membrane has retroreflective cube crystalline substance microstructure 020, and Counter-reflection membrane incident ray 410 reaches inverse
After reflectance coating 100, triple reflection is carried out in the square plane of reflection of 90 degree of orthogonally located three, and ultimately form inverse
Reflectance coating reflection light 420,420 direction of Counter-reflection membrane reflection light and former Counter-reflection membrane incident ray 410 are consistent, but propagate
It is contrary.Meanwhile in reflection process, 420 position of Counter-reflection membrane reflection light and 410 position of Counter-reflection membrane incident ray are generated
Certain displacement.
When above-mentioned reflection is formed by Counter-reflection membrane reflection light 420 by Lenticular screen, it can be rolled over by Lenticular screen
It is incident upon other vertical transmission directions different from incident light.Cylindrical lens refracting process 030 please refers to Fig. 3.Counter-reflection membrane incident light
There are certain displacement between line 410 and Counter-reflection membrane reflection light 420, which makes Counter-reflection membrane reflection light 420 in cylindrical lens
Incidence point on grating is not overlapped with Counter-reflection membrane incident ray 410, and is refracted to by Lenticular screen 200 different from incident light
Other vertical direction.
The horizontal direction light splitting principle of this reflex reflection stereo projection display apparatus 010 please refers to Fig. 4.Because of Lenticular screen
200 only arrange in vertical direction, and in horizontal direction and indistinction, therefore Counter-reflection membrane reflection light 420 is refracted into other hangs down
When the straight direction of propagation, horizontal transmission direction is remained unchanged.Therefore final Counter-reflection membrane reflection light 420 is on horizontal transport is reversed
300 place horizontal position of projector is converged to, and forms viewpoint.Human eye can see the projector when being in the viewpoint position
The anaglyph of 300 projections.
The vertical direction light splitting principle of this reflex reflection stereo projection display apparatus 010 please refers to Fig. 5.Because of Counter-reflection membrane incidence
Existing displacement is not constant between light 410 and Counter-reflection membrane reflection light 420, therefore Counter-reflection membrane reflection light 420 is saturating by column
After mirror grating 200 reflects, there is beam projecting in any vertical direction.Therefore when human eye is in and 300 horizontal position of projector
When setting identical any vertical orientations, it can be seen that the image that the projector 300 projects.
In the present embodiment, four projectors 300 reflect through Counter-reflection membrane 100 and column for projecting four width anaglyphs
After lenticulation 200 reflects, the horizontal position of Yu Sitai projector 300 forms four different points of view, when viewer's right and left eyes
When being respectively at the horizontal position at different 300 places of projectors, corresponding anaglyph can be respectively seen, to generate
Stereoscopic vision.In the present embodiment, since the position and structure of Lenticular screen 200 and Counter-reflection membrane 100 are not necessarily to special matched, therefore
It is lower to the requirement of optical texture matched measure of precision relative to the conventional stereo projection display, convenient for promoting manufacture.
