Abstract : A shield or opaque covering for reducing blooming at low input levels in two-dimensional charge-injection devices. Two-dimensional charge-injection devices include X-Y aligned detector elements in which each detector element includes a y-electrode portion and a x-electrode portion, each in the same alignment. Each of the y-electrode portions in the same vertical column is connected to a common conductor to form separate y-electrode column conductors, one for each column of elements. Each of the x-electrode portions in the same horizontal row is connected to a common conductor thereby forming separate rows of x-electrode conductors, one for each row of elements. During fabrication each of the rows of y-electrode portions is permanently covered with a covering which is opaque to the radiation to be detected whereas each of the x-electrode areas is exposed to the radiations to be detected. Such an arrangement permits read-out of individual detector elements without blooming by nearby detector elements at low inputs. (Author)
