Abstract: Described are an imaging device and method for determining three-dimensional position information of a surface of an object. The device includes a pair of optical fibers, a phase shifter, a detector array and a processor. The phase shifter is coupled to one of the optical fibers and is used to change a phase of optical radiation emitted from the optical fiber relative to a phase of optical radiation emitted from the other optical fiber. The detector array receives optical radiation scattered by the surface of the object. The processor communicates with the detector array and the phase shifter. Signals generated by the detector array are received by the processor and three-dimensional position information for the surface is calculated in response to the received optical radiation scattered by the surface of the object and the change in the relative phase of optical radiation emitted by the optical fibers.

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: Described is an interferometric surface contour measurement system for projecting structured light patterns onto an object. The measurement system includes an interferometric projector, an imager, and a processor. The imager is rigidly coupled to the projector to maintain a stable relationship to the projected, structured light pattern. The imager receives the structured light pattern and together with the processor, determines whether the projected image includes a positional error. In some embodiments, the projector is a multi-channel projector, each channel having an optical axis spatially separated from the others, one of the channels including the imager and dedicated for determining positional error. In other embodiments, the projector is a single-channel projector projecting a structured light pattern onto the object, a portion of the structured light pattern being tapped-off for determining positional error.

Abstract: An apparatus for allocating communication channels in a manner that increases network efficiencies or operator revenue includes a resource manager that accepts and stores (forms a queue) resource requests for a period of time. Thereafter, the resource manager allocates resources according to specified criteria. The computer instructions stored within the resource manager includes logic to prompt it to allocate communication channel resources according to the size (in order of smallest to largest) of the requested resource, or to the unit value of the requested resources. The communication channels are characterized by a time slice of a signal transmitted at a specified frequency range. Prior to allocating new non-CBR communication channel resources according to size or to unit value, the communication channels are first allocated to legacy continuous bit rate (CBR) subscribers, then to legacy non-CBR subscribers, then to new CBR subscribers.

Abstract: An electro-optical, ridge-waveguide device and method for its fabrication utilizes a polyimide ridge-protection layer, which provides good ridge protection/planarization while minimizing parasitic capacitance. A silicon oxide interlayer is used between a metal contact layer and the polyimide. This interlayer facilitates the adhesion between the metal contact layer and the underlying device since good adhesion can be obtained between the silicon oxide layer and the polyimide layer and between the metal layer and silicon oxide layer. Preferably, the polyimide is roughened to increase the surface area contact between the polyimide layer and silicon oxide layer to further increase adhesion and thus the pull-off force required to separate the metal contact layer from the device. While such roughening can be achieved through plasma etching, in a preferred embodiment, the polyimide layer is roughened by patterned etching.
