Abstract
A synchronously gated high speed CCD imager system having a predetermined frame time includes: a CCD interline transfer array including a plurality of photoelectric collection quantum wells for collecting photoelectrons from an object; a plurality of storage wells associated with the collection wells; an anti-blooming circuit for diverting photoelectrons from accumulating in the collection wells; and switching means for transferring the photoelectrons accumulated in the collection wells to the storage wells and enabling the anti-blooming circuit during synchronized portions of the frame time to divert photoelectrons from accumulating in the collection wells and for disabling the anti-blooming circuit to enable the collection wells to collect photoelectrons during another portion of the frame time.
