Charge coupled devices in tiled arrays

摘要

Charge coupled devices (CCDs) can be placed next to each in a tiled array to reproduce a larger image. The seams between the CCDs in a tiled CCD array can be reduced by placing fiber optic arrays on top of each CCD in the CCD array. The fiber optic arrays have numerous optical fibers that are tilted with respect to the plane of the CCDs. The optical fibers can retrieve electromagnetic radiation falling in gaps between the tiled CCDs. The optical fiber arrays substantially reduce the seams that appear in the image. Electronic pixel binning configurations can be adjusted to accommodate the placement of the optical fibers. The fiber optic arrays can have beveled edges near the gaps between adjacent CCDs to image light in the gaps. Techniques for reducing the dead zone between CCDs in a tiled array and for forming fiber optic arrays on a common plane are also provided.
