ABSTRACT:
During the integration of odd fields, alternate row conductors of a charge injection device (CID) array successively are placed at an operating potential at which charge carriers photoexcited in the substrate may be collected at the CID's along each such row. Isolation between such rows is achieved by successively placing the intervening row conductors at a potential to form potential barriers in the substrate. During the integration of even fields, the roles of the row conductors are reversed. Operation in this way results in vertical interlace and it permits the charge collecting locations of the CID array to be spaced relatively close to one another in the column direction, that is, it permits relatively high resolution in the column direction.
