Abstract

A stereoscopic display cart and system providing a means of presenting stereoscopic images. Various embodiments are disclosed including an LCD and other monitor-based display means, as well as projector-based display means. A means of providing stereoscopic images can be a stereoscopic microscope or any other means providing stereoscopic images. Embodiments having folding components for compact transport and storage are disclosed, including embodiments having registration of position and orientation such that re-alignment is not required upon teardown, transport and re-deployment.

Claims

1. A stereoscopic display cart comprising:

a chassis providing physical support for the cart;

a vertical column coupled to the chassis and arising from the chassis;

a first arm supported by the vertical column; and

,

a display means supported by the first arm to display stereoscopic images.

2. The stereoscopic display cart of claim 1, wherein the display means is an LCD display.

3. A stereoscopic display system, comprising the stereoscopic display cart of claim 1 and a means of providing stereoscopic images to the stereoscopic display cart.

4. The stereoscopic display system of claim 3, wherein the means of providing stereoscopic images to the stereoscopic display cart is a stereoscopic microscope.

5. A stereoscopic display cart comprising:

a chassis providing physical support for the cart;

a vertical column coupled to the chassis and arising from the chassis;

a first arm supported by the vertical column;

one or more projectors supported by the vertical column projecting stereoscopic images; and

,

a display means supported by the first arm to display stereoscopic images projected by the one or more projectors.

6. The stereoscopic display cart of claim 5, wherein the vertical column can be extended vertically, thereby providing that the first arm and display means can be raised or lowered.

7. The stereoscopic display cart of claim 5, wherein the first arm can be adjusted vertically along the vertical column, such that the display means can be raised or lowered.

8. The stereoscopic display cart of claim 5, wherein the display means is a screen.

9. The stereoscopic display cart of claim 5, wherein the display means is a screen wherein the polarization of light passing from the rear of the screen through the screen and to a viewer is generally preserved.

10. The stereoscopic display cart of claim 5, further comprising one or more polarizers to oppositely polarize at least a portion of the stereoscopic images.

11. The stereoscopic display cart of claim 10, wherein the one or more polarizers polarize both a left view and a right view of the stereoscopic images.

12. The stereoscopic display cart of claim 10, wherein the one or more polarizers are comprised of one or more filters to remove light of a specific character.

13. The stereoscopic display cart of claim 5, further comprising a mirror for reflecting the stereoscopic images.

14. The stereoscopic display cart of claim 5, further comprising a plurality of mirrors for reflecting the stereoscopic images.

15. The stereoscopic display cart of claim 5, wherein the one or more projectors is a plurality of projectors, wherein the plurality of projectors comprises a left view projector and a right view projector.

16. The stereoscopic display cart of claim 15, further comprising a subassembly to configure the plurality of projectors.

17. The stereoscopic display cart of claim 5, further comprising a polarized spectacles to separate a left view and a right view from the stereoscopic images such that a viewer views stereoscopic images on the display means in stereoscopic vision.

18. The stereoscopic display cart of claim 5, wherein the first arm is foldable downward to a closed position for a compact configuration.

19. The stereoscopic display cart of claim 5, further comprising legs that can be folded outward or extended to provide additional stability of the display cart.

20. A stereoscopic display system, comprising the stereoscopic display cart of claim 5 and a means of providing stereoscopic images to the stereoscopic display cart.

21. The stereoscopic display cart of claim 20, wherein the means of providing stereoscopic images to the stereoscopic display cart is a stereoscopic microscope.

22. A stereoscopic display cart comprising:

a chassis providing physical support for the cart;

a vertical column arising from the chassis;

a first arm supported by the vertical column;

a second arm supported by the first arm;

a projector platform supported by the first arm;

one or more projectors supported by the projector platform, wherein the one or more projectors project stereoscopic images; and

,

a display means supported by the second arm to display stereoscopic images projected by the one or more projectors.

23. The stereoscopic display cart of claim 22, further comprising a cover supported by the second arm.

24. The stereoscopic display cart of claim 22, wherein the second arm can rotate about a vertical axis.

25. The stereoscopic display cart of claim 22, wherein the projector platform can rotate about a vertical axis.

26. The stereoscopic display cart of claim 22, wherein the second arm can be folded into a closed position for a compact configuration.

27. The stereoscopic display cart of claim 22, further comprising legs that can be extended to provide additional stability to the display cart.

28. A stereoscopic display system, comprising the stereoscopic display cart of claim 22 and a means of providing stereoscopic images to the stereoscopic display cart.

29. The stereoscopic display cart of claim 28, wherein the means of providing stereoscopic images to the stereoscopic display cart is a stereoscopic microscope.
