Abstract: A system for determining a dimension of a detail including an optical scope for producing an image of the detail, an image scaling device for providing a scaled image size, and a processor. The system also includes a video camera which is either within the optical scope or external to the optical scope. The optical scope includes a focusing device for adjusting a focal position of the image of the detail and a device for providing a focus position signal based a position of the focusing device. If the system includes an external video camera, the optical scope also includes a viewer for passing the image of the detail to a plane outside of the optical scope. The video camera optically is coupled with the viewer of the optical scope or with the image of the detail and produces a video signal of the detail from the image of the detail.

Abstract: A device, having a case body and case lid, for use with a remote visual inspection system. The case body is adapted to accommodate a light source for providing light to the remote visual inspection system. The case lid is adapted to cover the case body, and to accommodate a video display monitor for displaying an image captured by the remote visual inspection system.

Abstract: A coherent fiberoptic display for a region having strong magnetic field. Transfer optics launch the image into one end of a coherent fiberoptic bundle that transfers the image to the display. Transfer optics at the other end of the coherent fiberoptic bundle direct the image to a fiberoptic taper. The image is viewed on the expanded end of the fiberoptic taper. The image can comprise a video image formed by a CRT located in a region of low magnetic flux density and the fiberoptic taper can be positioned in the imaging zone of a Magnetic Resonance Imaging (MRI) apparatus. The video image can allow the patient to watch television during magnetic resonance imaging. This distraction will reduce the anxiety experienced during magnetic resonance so that the patient is less apt to move and the magnetic resonance images are less apt to be blurred or destroyed. The efficiency of magnetic resonance imaging is thus improved.
