Abstract

A stereoscopic microscope workstation providing high-resolution, real-time video signals to a display device. A stereoscopic microscope workstation providing high-resolution, real-time data to a display means. 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 performing a procedure of simultaneously utilizing both foveal vision and peripheral vision.

Claims

1. A stereoscopic microscope workstation for a user to view an object as a stereoscopic 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;

at least one high-resolution camera configured to;

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

(b) combine real-time image data acquired from the plurality of optical views into a single data structure, the real-time image data having a resolution of at least 1280×

720 pixels for at least one of the optical views; and

(c) transmit, in real-time, the single data structure;

at least one high-resolution display device configured to;

(a) receive the single data structure; and

(b) display, using the received single data structure, a magnified image of the object to the user, at least one of the at least one high-resolution display device having a resolution of at least 1280×

720 pixels; and

at least one deflecting element disposed between the object and the stereomicroscope, wherein the at least one deflective element provides a change in a location of a viewing point of the object in the magnified image by rotating about an axis.

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

3. The stereoscopic microscope workstation of claim 1, wherein the one or more high-resolution 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.

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

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

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

7. 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.

8. The stereoscopic microscope workstation of claim 7, wherein the holder includes a stage, the stage being configured to quantify the relative distance of points-of-interest on the object to provide measurement capabilities.

9. 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.

10. The stereoscopic microscope workstation of claim 9, wherein the mounting system is configured to quantify the relative distance of points-of-interest on the object to provide measurement capabilities.

11. A method of operating a stereoscopic microscope workstation, the method comprising:

(a) acquiring, by a stereomicroscope, a plurality of optical views of the object;

(b) providing, by the stereomicroscope, a plurality of optical paths of the plurality of optical views;

(c) acquiring, by a stereoscopic image acquisition device, the plurality of optical paths from the stereomicroscope;

(d) combining, by the stereoscopic image acquisition device, real-time image data acquired from the plurality of optical views into a single data structure, the real-time image data having a resolution of at least 1280×

720 pixels for at least one of the optical views;

(e) transmitting, in real-time by the stereoscopic image acquisition device, the single data structure;

(f) receiving, by a display device, the single data structure;

(g) displaying, by the display device, a stereoscopic magnified image of the object to the user;

(h) enabling a user to focus on the magnified image with the user'"'"'s foveal vision; and

(i) enabling the user to view a manipulation of a tool with the user'"'"'s peripheral vision, while not losing foveal vision focus on the magnified image of the object,

wherein steps (a)-(i) are performed by a stereoscopic microscope workstation as defined in claim 1.

12. The method of claim 11, wherein the manipulation of the tool comprises changing a hand tool.

13. The method of claim 11, wherein the manipulation of the tool comprises positioning the tool closer to the object.

14. A method of operating a stereoscopic microscope workstation, the method comprising:

(a) acquiring, by a stereomicroscope, a plurality of optical views of the object;

(b) providing, by the stereomicroscope, a plurality of optical paths of the plurality of optical views;

(c) acquiring, by a stereoscopic image acquisition device, the plurality of optical paths from the stereomicroscope;

(d) combining, by the stereoscopic image acquisition device, real-time image data acquired from the plurality of optical views into a single data structure, the real-time image data having a resolution of at least 1280×

720 pixels for at least one of the optical views;

(e) transmitting, in real-time by the stereoscopic image acquisition device, the single data structure;

(f) receiving, by a display device, the transmitted single data structure;

(g) using the received single data structure, displaying, by the display device, a stereoscopic magnified image of the object to a user; and

(h) enabling the user to focus on a manipulation of a tool with the user'"'"'s foveal vision, while viewing the magnified image of the object with the user'"'"'s peripheral vision;

wherein steps (a)-(i) are performed by a stereoscopic microscope workstation as defined in claim 1.

15. The method of claim 14, wherein the manipulation of the tool comprises changing a hand tool.

16. The method of claim 14, wherein the manipulation of the tool comprises positioning the tool closer to the object.
