    Abstract: Described is a multiple channel interferometric surface contour measurement system. The measurement system includes a multiple channel interferometer projector, a digital camera and a processor. The projector includes two or more interferometer channels. Each channel has an optical axis spatially separate from the optical axes of the other channels. Each channel projects a fringe pattern onto the surface of an object to be measured. Image data for the fringe patterns projected on the object surface are acquired by the digital camera. The processor controls the projection of the fringe patterns of different spatial frequencies, adjusts the phase of each fringe pattern and generates surface contour data in response to the camera image data. The multiple channel interferometric surface contour measurement system provides numerous advantages over conventional single channel interferometric systems, including reduced sensitivity to optical noise, improved stability and increased measurement accuracy.

    Abstract: A measuring apparatus for determining the location of a point in space using a coordinate measuring machine, such as a laser tracker. The apparatus comprises a retroreflector releasably coupled to a sphere of a tooling ball. The tooling ball is rigidly coupled to a mechanism whose position is to be found and whose movements can be monitored by repeatedly determining the position of the center point of the sphere of the tooling ball. The retroreflector is formed of solid glass and has a corner cube having a vertex which has a predetermined dimensional relationship with and represents the virtual location of the point in space, that is, the center point of the sphere. The retroreflector is configured to receive a beam of light from the laser tracker and then reflect and retroreflect the beam to the laser tracker to determine the location of the vertex of the corner cube and, thus, the center of the tooling ball. The retroreflector is movable along the outer surface of the sphere of the tooling ball and maintains the various positions to which it is moved in a free-standing manner without any external assistance or support. Additionally, the retroreflector is easily removed from the tooling ball and placed on the same or other tooling balls.

    Abstract: A real time analysis of nuclear reactor vessel integrity is preformed by monitoring reactor coolant temperature and pressure and fast neutron fluence, and generating therefrom a visual comparison of the reference nil-ductility transition temperature, RT.sub.ndt, required for flaw initiation and the actual RT.sub.ndt through the entire depth of the vessel wall at selected critical locations. When flaw initiation is indicated at any depth, the RT.sub.ndt required for flaw propagation arrest is also generated and displayed. A display can also be generated to provide guidance for optimum performance during heatup and cooldown. Thermocouples located at the reactor core inlet are used in conjunction with the resistance temperature detectors, RTDs, conventionally provided in the cold leg conduits to generate a more accurate measurement of the coolant temperature at the critical locations in the vessel. Under stagnant flow conditions a correlation is applied to the RTD readings to provide the best estimate of coolant temperature at the critical locations.
