  • Publication number: 20140336460
    Abstract: Two side-by-side optical paths transmit stereoscopic right side and left side images onto the surface of a single image sensing chip. The single image sensing chip may be placed at various orientations with respect to the lens trains in the optical paths. In some embodiments a single prism is used to turn the light for both the right side and left side images onto the single image sensing chip. In other embodiments one prism is used to turn the light for the right side image and another prism is used to turn the light for the left side image, and the reflective surfaces of the two prisms are substantially coplanar such that the right side and left side images are incident on the single image sensor chip.

  • Publication number: 20030202091
    Abstract: A modular assisted visualization system includes an image manipulation module in communication with a work piece manipulation device, a camera module and at least one remote image manipulation module. The camera module, which is coupled to the work piece manipulation device and includes a camera lens and a light, provides a visual image of a work area of the work piece manipulation device. The visual image provided is displayed on the image manipulation module. The image manipulation module lays down at least one of a grid and a cut line on a work piece, by using the camera lens. The grid or cut line is established by data received by the image manipulation module from an operator. The work piece manipulation device, controlled by the image manipulation module, is engaged upon the grid or cut line established on the work piece.
