Abstract
Accordingly, the present invention is directed to providing methods and apparatus for detecting light energy in real-time while minimizing the effects of background charge accrual on the charge-coupled device. Exemplary embodiments provide relatively fast electronic shuttering and exposure control to minimize accrual of unwanted background illumination. Further, exemplary embodiments can be operated at relatively high speeds without increasing the complexity of electronics used to drive the charge-coupled device or process information produced by the charge-coupled device.
