Abstract

A stereoscopic microscope workstation providing high-resolution, real-time data to a display device. Various embodiments are disclosed including desktop and free-standing workstations. An image processing unit can be implemented, providing for natural orientation of the magnified image of the viewed object, also allowing rotation, cropping, filtering and other image manipulation features. Methods of performing a procedure utilizing the stereoscopic microscope workstation are disclosed, including a method of manipulating an object while viewing the object in a high-resolution real-time magnified image.

Claims

1. A stereoscopic microscope workstation for a user to view an object as a magnified image, comprising:

a stereomicroscope configured to;

(a) acquire a plurality of optical views of the object; and

(b) provide a plurality of optical paths of the plurality of optical views;

a stereoscopic image acquisition device configured to;

(a) acquire the plurality of optical paths from the stereomicroscope; and

(b) transmit a real-time image data stream representing the plurality of optical paths;

a display device configured to;

(a) receive the real-time image data stream; and

(b) display a stereoscopic magnified image of the object to the user; and

a deflecting element disposed between the object and the stereomicroscope, the deflecting element providing a change in a location of a viewing point of the object by rotating about an axis.

2. The stereoscopic microscope workstation of claim 1, wherein the real-time image data stream has a resolution of at least 1280×

720 pixels for at least two of the optical views of the plurality of optical views.

3. The stereoscopic microscope workstation of claim 1, wherein the magnified image of the object is displayed in the same orientation as the object.

4. The stereoscopic microscope workstation of claim 1, which includes an image processing unit configured to manipulate the real-time image data stream prior to the display device receiving the real-time image data stream, the image processing unit being separate from the stereoscopic image acquisition device.

5. The stereoscopic microscope workstation of claim 4, wherein the image processing unit for manipulating the real-time image data stream is configured to rotate, crop, invert, mirror and filter the real-time image data stream.

6. The stereoscopic microscope workstation of claim 4, wherein the image processing unit for manipulating the real-time image data stream is affixed to the stereoscopic microscope workstation.

7. The stereoscopic microscope workstation of claim 1, wherein the display device comprises a single flat LCD display device, such that the user wears differently-polarized spectacles to achieve a stereoscopic view of the object in the magnified image.

8. The stereoscopic microscope workstation of claim 1, wherein the display device comprises separate left and right views.

9. The stereoscopic microscope workstation of claim 1, wherein the stereoscopic microscope workstation is configured in a free-standing configuration.

10. The stereoscopic microscope workstation of claim 1, wherein:

(a) the stereomicroscope is disposed above a line of sight of the user; and

(b) the stereoscopic image acquisition device is disposed above the line of sight of the user.

11. The stereoscopic microscope workstation of claim 1, wherein the deflective element is configured to change a central optical axis of the plurality of optical paths.

12. The stereoscopic microscope workstation of claim 1, which includes spectacles, at least a portion of the spectacles being polarized, thereby providing a stereoscopic view of the magnified image of the object.

13. The stereoscopic microscope workstation of claim 1, which includes a holder configured to hold the object, thereby controlling the position and motion of the optical views of the object.

14. The stereoscopic microscope workstation of claim 13, wherein the holder includes a stage configured to quantify the relative distance of points-of-interest on the object to provide measurement capabilities.

15. The stereoscopic microscope workstation of claim 1, which includes a mounting system configured to control the position and motion of the optical views of the object.

16. The stereoscopic microscope workstation of claim 15, wherein the mounting system is configured to quantify the relative distance of points-of-interest on the object to provide measurement capabilities.

17. A stereoscopic microscope workstation for a user to view an object as a magnified image, comprising:

a stereomicroscope configured to;

(a) acquire a plurality of optical views of the object; and

(b) provide a plurality of optical paths of the plurality of optical views;

a stereoscopic image acquisition device configured to;

(a) acquire the plurality of optical paths from the stereomicroscope; and

(b) transmit a high-resolution real-time image data stream representing the plurality of optical paths, the high-resolution real-time image data stream having a resolution of at least 1280×

720 for at least two of the optical views in the plurality of optical views;

an image processing unit configured to manipulate the real-time image data;

a display device configured to;

(a) receive the high-resolution real-time image data stream; and

(b) display a stereoscopic magnified image of the object to the user;

the stereoscopic magnified image of the object being presented in the same orientation as the object; and

a deflecting element disposed between the object and the stereomicroscope, the deflecting element providing a change in a location of a viewing point of the object by rotating about an axis.

18. The stereoscopic microscope workstation of claim 17, which includes spectacles, a portion of the spectacles being polarized, the display device including a single flat LCD display device providing stereoscopic views of the magnified image of the object.

19. The stereoscopic microscope workstation of claim 17, wherein the stereoscopic microscope workstation is configured in a free-standing configuration.
