Charge injection device evaluation hardware

A microprocessor based system which provides maximum testing flexibility via software reconfiguration is described. This system has the capability to evaluate a charge injection device (CID) and to characterize its performance. The construction and operation of the CID offer advantages over the various CCD configurations available. These advantages include a less sophisticated manufacturing process, no images smearing during readout, high transfer efficiencies, and high resistance to blooming due to optical overload.
