An apparatus for storing a time varying analog signal n real time for later read out, comprising:
- means for sequentially breaking up a time varying signal having an amplitude into discrete time intervals, said means for breaking up including means for supplying an electron beam;
- means for deflecting said electron beam in accordance with said time varying signal, means for further deflecting said electron beam along an axis substantially perpendicular to that axis along which said beam is deflected with said time varying signal
- means for detecting and storing said deflected electron by means of an array of rectangularly shaped charge detector elements;
- and
- means for taking each of said charges from said detector elements so that said charges can be read at a lower rate than the rate at which said charges were originally stored.
