Abstract

An image projection system capable of projecting images to multiple screens or viewing surfaces. The system uses a moveable mirror to direct the projected images to the screens. The moveable mirror may work in concert with one or more fixed mirrors to reflect the projected images to screens in a variety of configurations relative to the projector.

Claims

1. A multiple-image projector system comprising:

an image projector for projecting a light image;

a plurality of screens;

a plurality of fixed mirrors;

a moveable mirror placed in the path of the projected light image and positionable to reflect the projected light image to a selected fixed mirror; and

wherein each fixed mirror is positioned to reflect the projected light image to one of the plurality of screens.

2. The multiple-image projector system of claim 1 wherein said moveable mirror is positioned by a motor means.

3. The multiple-image projector system of claim 1 further comprising means for moving the moveable mirror to reposition the projected light image sequentially onto each fixed mirror in a loop at a cycle frequency such that the image projected to the screen appears constant to a viewer of the image.

4. The multiple-image projector system of claim 1 further comprising means for moving the moveable mirror in a flip-flop manner to reposition the projected light image onto a selected fixed mirror.

5. The multiple-image projector system of claim 1 wherein one or more of the screens is opaque.

6. The multiplex-image projector system of claim 1 wherein one or more of the screens is translucent.

7. The multiple-image projector system of claim 1 wherein the moveable mirror has more than one reflecting surface.

8. A multiple-image projector system comprising:

an image projector for projecting a light image;

a plurality of screens; and

a moveable mirror placed in the path of the projected light image and positionable to reflect the projected light image to a selected one of the plurality of screens, wherein said moveable mirror is positioned by a motor means.

9. The multiple-image projector system of claim 8 further comprising means for moving the moveable mirror in a flip-flop manner to reposition the projected light image onto a selected screen.

10. The multiple-image projector system of claim 8 wherein one or more of the screens is opaque.

11. The multiple-image projector system of claim 8 wherein one or more of the screens is translucent.

12. A multiple-image projector system comprising:

an image projector for projecting a light image;

a screen with first and second projectable sides;

first and second fixed primary mirrors;

a moveable mirror placed in the path of the projected light image and positionable to reflect a projected light image to a selected fixed primary mirror; and

a plurality of fixed secondary mirrors each positioned to receive the projected light image from a fixed primary mirror and to reflect the projected light image onto said screen.

13. The multiple-image projector system of claim 12 wherein said moveable mirror is positioned by a motor means.

14. The multiple-image projector system of claim 12 further comprising means for moving the moveable mirror to reposition the projected light image sequentially onto the first and second fixed primary mirrors in a loop at a cycle frequency such that the image projected to the screen appears constant to a viewer of the image.

15. The multiple-image projector system of claim 12 wherein the screen is opaque.

16. The multiple-image projector system of claim 12 wherein the screen is translucent.

17. The multiple-image projector system of claim 12 wherein the screen'"'"'s ability to pass through light is variable.

18. The multiple-image projector system of claim 12 wherein the moveable mirror has more than one reflecting surface.

19. The multiple-image projector system of claim 12 further comprising means for moving the moveable mirror in a flip-flop manner to reposition the projected light image onto a selected fixed mirror.

20. A multiple-image projector system comprising:

an image projector for projecting a light image;

a plurality of fixed holographic mirrors;

a plurality of moveable mirrors placed in the path of the projected light image and positionable to reflect the projected light image to a selected fixed mirror; and

wherein each fixed holographic mirror is positioned to reflect the light image to a holographic display medium.
