摘要： A coherent optical receiver circuit is disclosed in which various components of the optical receiver may be provided or integrated, in one example, on a common substrate. Further integration is achieved by incorporating various optical demultiplexer designs that are relatively compact and conserve space on the surface of the substrate. The optical receiver circuit may be used to demultiplex quadrature phase shift keying (QPSK) optical signals.

摘要： This invention is a preprocessor apparatus and method algorithm facilitating black bar detection in video frames or fields. The preprocessing marks a sharp discontinuity between pixels a predetermined distance apart on each line. On first detection of this discontinuity the location and pixel value is stored. The location and pixel value is also stored for the last discontinuity in the line. This data enables software to detect top horizontal bars, bottom horizontal bars, left vertical bars and right vertical bars.

摘要： A scanning exposure apparatus of the present invention is one for transferring a pattern of a first object onto a second object while projecting an image of the first object placed on a first plane, onto the second object placed on a second plane and changing a positional relation between the image of the first object and the second object in a scanning direction. The scanning exposure apparatus has a first projection optical system having a first field of view on the first plane and adapted to project an enlargement image of a portion of the first object in a first projection region on the second plane, based on light from the first field of view, and a second projection optical system having a second field of view on the first plane and adapted to project an enlargement image of a portion of the first object in a second projection region on the second plane, based on light from the second field of view. The scanning exposure apparatus satisfies the relation of Dp=β×Dm, where Dm is a first interval being an interval along the scanning direction on the first plane between the first field of view and the second field of view, Dp is a second interval being an interval along the scanning direction on the second plane between the first projection region and the second projection region, and β is a magnification of the first and second projection optical systems.
