Abstract: An array of radiation sensing devices each including a pair of closely coupled conductor-insulator-semiconductor cells, one a row line connected cell and the other a column line connected cell, is provided on a common semiconductor substrate. The potential well associated with the row connected cell is deeper than the potential well associated with the column connected cell. Read out of a row of devices is accomplished by lowering the absolute potential of the row line to cause charge stored in the row connected cells to transfer to column connected cells of the row. The voltage on each of the column lines is sensed in sequence to provide a video signal. Subsequent to sensing the column line potentials can be lowered to inject the stored carriers into the substrate or the row line potential may be reestablished to return the stored charge to the potential wells associated with the cells connected to the row lines and thus permit repeated read out.
