Operation of CCD's with stationary and moving electron-beam input

For the detection of either stationary or moving objects in a LLLTV (low light level TV) environment with a charge coupled device (CCD), two techniques have been demonstrated which will result in improved detection. These are 1) use of an EBS (electron bombarded silicon) or EBIC Mode CCD which provides gain by accelerating photogenerated electrons and 2) use of a motion compensation mode where charge packets are shifted in unison with a (constant velocity) target.
