Abstract
A circular scan streak tube system for recording fast optical data includes a target having a first array of detection elements and a second array of corresponding storage elements. Changes in the scanning electron beam current representing optical events are detected and stored in the first array. The first and second arrays are segmented into two halves for continuous operation. Data stored in one half of the first array are transferred into the corresponding storage elements while data are written into the other half of the first array. Data stored in the first array are transferred in parallel to the second array. After a triggering event, the data are shifted circumferentially through the second array for output as serial data. The target is formed in a unitary planar semiconductor substrate having a buried channel for storing and conducting electric charge representing the stored data.
