A 3072 × 32-stage TDI charge-coupled imaging device is described. It is believed to be the first reported TDI imager suitable for 300-pel-per-inch document scanning. Its large photocharge capacity gives it the noise performance and dynamic range required for high-quality gray-scale and color imaging in publishing and museum applications. Design options for high-resolution TDI imagers and the uniformity enhancement provided by the TDI mode of operation are discussed.
