Abstract: An integrated endoscope and visualization system comprises an endoscope, a visualization processing module and a 3D display device such as smart-glasses or naked-eye 3D display. The endoscope is equipped with two image capturing modules such as CMOS image sensors and can be disposable. The visualization processing module receives and encodes the images obtained by the two image capturing modules in order to generate an output visualization signal. The output visualization signal is transmitted to and displayed by the 3D display device in a 3D manner. The integrated endoscope and visualization system not only provides a 3D vision of surgical target during an endoscopic surgery operation, but also allow the medical personnel to walk or move during the surgery while keeping looking at the 3D images captured by the endoscope through wearable display devices.

Abstract: The see-through eyepiece includes a first prism, a second prism, and a partially reflective layer. The first prism has an input surface, a flat first total internal reflection surface, and a first interface surface. The second prism has a second interface surface, a flat second total internal reflection surface, and a reflection surface. The partially reflective layer is disposed between the second interface surface and the first interface surface. The second and first prisms are attached together along the second and first interface surfaces, thereby forming the complete see-through eyepiece. The present invention is able to reduce the traversal distance of light within the prisms, effectively lowering the thickness of the see-through eyepiece, or enhancing its field or angle of view. A user may perceive images more easily and conveniently, achieving better product performance and applicability.

Abstract: A passive control system for taking a three dimensional picture comprises a 2D-3D converting device, and a rotary disk apparatus. The 2D-3D converting device at one end thereof connects with a digital picture taking apparatus via a shift interface and at the other end thereof connects with a data processing center. The 2D-3D converting device provides a preset program to regulate the digital picture taking apparatus with a start of scanning at a preset time. The rotary disk apparatus provides a positioning interface to connect with a rotary disk thereof and the rotary disk is able to stay in place after turning a preset angular displace in accordance with the preset program. An object to be taken a picture is placed on the rotary disk and is taken a picture by the digital picture taking apparatus as soon as the rotary disk is turned the preset angular displacement once.
