摘要:
A synchronously gated high speed CCD imager system (12) having a predetermined frame time includes: a CCD interline transfer array including a plurality of photoelectric collection quantum wells (14, 16) for collecting photoelectrons from an object; a plurality of storage wells (18, 20) associated with the collection wells; an anti-blooming circuit (30) for diverting photoelectrons from accumulating in the collection wells; and switching means (33) 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 antiblooming circuit to enable the collection wells to collect photoelectrons during another portion of the frame time.
