ABSTRACT:
A CCD imager is made to have an internal drift field tending to force further into the bulk any charge carriers outside the potential wells induced adjacent to integrating electrodes, so those charge carriers recombine in the bulk. This reduces background striations, reduces crosstalk, can be used for improving blooming control, and can be exploited to control the wavelengths of light to which the imager is responsive.
