In order to three-dimensional record and broadcasting can be carried out to scene, need first to use 3-D photography device to carry out recording and undertaken projecting to manifest 3-D view by three-dimensional projection device again.Conventional three-dimensional projection device comprises controller, the first projection light source, the second projection light source, the first LCD panel, the second LCD panel, the first projection lens and the second projection lens; The image information of the 3-D view that controller projects as required exports control signal respectively to the first LCD panel and the second LCD panel; As beam modulator, first LCD panel is modulated the light beam that the first projection light source produces and goes out from the first projection lens projects with being controlled by the controller, second LCD panel is modulated the light beam that the second projection light source produces and goes out from the second projection lens projects with being controlled by the controller, the light beam that two camera lenses project superposes mutually, manifests 3-D view.
Because controller exports control signal respectively to the first LCD panel and the second LCD panel, wayward the two synchronously light beam is modulated, in addition, whole three-dimensional image forming apparatus needs use two to overlap driving circuit to drive beam modulator.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of projection arrangement of three-dimensional imaging.
In order to realize above-mentioned fundamental purpose, the utility model provides a kind of projection arrangement of three-dimensional imaging, and it comprises controller, projection light source, the first projection lens, the second projection lens and one and modulates for the light beam produced projection light source and project the beam modulator of two light beams; Controller exports control signal to beam modulator; Go out from a branch of light beam the two light beams that beam modulator projects from the first projection lens projects, another light beams goes out from the second projection lens projects, for manifesting 3-D view.
From above scheme, compared with prior art, less with the driving circuit of a set of beam modulator, not only can effectively reduce its volume, can be used in the higher equipment of volume requirement, and reduce costs; If adopted when a projection focus adjusting mechanism carries out synchronous-focusing to two projection lens, there is not the problem needing to carry out two beam modulators to be modulated to co-planar arrangement, simplify the assembly technology of three-dimensional projection device.In addition, be convenient to the modulation of controller control synchronization and produce the light beam being projected to two projection lens, be convenient to synchronously carry out projection two two dimensional images, superposition manifests 3-D view.
Concrete scheme is beam modulator is dmd chip, and projection light source comprises the plus lens of luminophor and the light path arrangement of light beam that produces along this luminophor successively, colour wheel and extender lens.
Another concrete scheme is beam modulator is LCD panel.
Preferred scheme is for also to comprise projection focus adjusting mechanism, this projection focus adjusting mechanism comprises a projection focusing actuator for driving the first projection lens and the second projection lens to carry out synchronous-focusing simultaneously, and controller exports focusing control signal to projection focusing actuator.
From above scheme, be convenient to two projection lens and synchronously focus.
