Abstract: In one instance, an optical interconnection is embedded in a structure. The optical interconnection embedded in the structure enables interfacing electrical subsystems and sharing electrical signals across the structure by converting electrical signals into optical and vice a versa by means of the optical data pipe technology. The system of these teachings enables methods for decreasing the weight and size of the system, for decreasing sensitivity to electromagnetic interference and for obtaining data from the interior of a system.

Abstract: A measuring apparatus is conveniently used without a support such as a tripod, and simply measures a relative distance between two arbitrary points, i.e. two arbitrary measurement target objects, without restriction as to the positions of the measurement target objects. Further, the measuring apparatus realizes a very simple measurement process, so that a user can have faith in the measured distance. The measuring apparatus allows first and second indicators to be easily oriented towards the two points that the user wants to measure using the manipulation of the first and second indicators.

Abstract: Provided is an apparatus and method for determining stereo disparity based on two-path dynamic programming and GGCP. The apparatus includes a pre-processing unit for analyzing texture distribution of an input image by using a Laplacian of Gaussian (LOG) filter and dividing the input image into a homogeneous region and a non-homogeneous region; a local matching unit for determining candidate disparities to be included in an each pixel of all pixels; a local post-processing unit for removing candidate disparities in a pixel of low reliability by performing a visibility test betweens candidate disparities in each pixel to improve the reliability of the candidate disparity; and a global optimizing unit for determining a final disparity for candidate disparities in an each pixel by performing a dynamic programming.

Abstract: An apparatus is provided for gravitation-compensated mounting of a measurement object (2) having a plurality of supporting elements (1) which each act at at least one point on the measurement object (2), with the supporting elements (1) being designed such that they exert a constant force when small changes occur in the position of the measurement object (2).

Abstract: A positioning and measuring station for photoelectric elements includes a base, a platen, a five-axis driving module and a retaining member. The platen is for holding a measuring object. The five-axis driving module is located between the base and the platen for driving the platen axially with respect to X, Y and Z axes, or rotatable on a plane or tiltable against a plane relative to the base. The retaining member is located on one side of the platen to dynamically adjust the extending distance of the platen so that the measuring object may be leaned thereon for alignment to define the holding position of the measuring object on the platen.

Abstract: An immersive scanning camera provides for a high speed imager to capture a scene of interest on a pixel by pixel basis. Distance data is collected for each pixel. This distance data is representative of the distance from the immersive camera of the object depicted by the pixel data.

Using a one-dimensional micromirror array, a fiber-optic based MEMS switched spectrometer that does not require mechanical motion of bulk components or large diode arrays can be constructed with readout capability for WDM network diagnosis or for general purpose spectroscopic applications.

Abstract: A device to measure the relative location in three dimensional space of anatomical structures by injecting a beam of light into an optical imaging device and projecting the beams of light onto the object being imaged. By virtue of the change in the image of the light beam, as a function of changes in the position and/or direction of the injected beam, and knowing the optical transfer function of the imaging device, the position of the anatomical structure can easily be calculated.

Abstract: An operating microscope has extensions on which are mounted neon lasers which focus beams through the focal point on the optical axis of the operating microscope. The beams produce two spots on an object when the object is away from the focal point, and a single spot on an object at a the focal point. Lightweight laser ring gyroscopes are connected to the operating microscope to determine spatial changes in the position and direction of the operating microscope and the focal point of the microscope.

Abstract: A bearing bush with a side opening is mounted within a telescope barrel. The telescope thus may be easily mounted on a tilting axis by simply inserting an axle into the bush. Mounting and adjustment of the tilting axis within its bearings and of angular measuring systems is thus independent of mounting of the telescope.
