Abstract
A sampling streak oscilloscope responsive to a light input signal stores charges on a CCD target by means of an electron beam rapidly scanned across a narrow dimension of the CCD target in coincidence with a segment or portion of the light input signal. The time relationship between a streak and the light input signal is changed to record a charge pattern for another segment of the input signal, while charges representative of a prior segment are transferred along the CCD array. A representation of the entire input signal is built up in memory.
