Abstract
A new electron trapping material is described together with a preliminary characterization. The material is used for correlation in the space domain between many stored images and an incoming image. As the material may be written and read it is possible to store the images against which the input is to be matched on film and then to map these one at a time onto the material for correlation. It would be useful if the material could be used for matched filtering in the frequency domain because this provides shift invariance. The difficulty of having different frequencies for read and write is shown to be unimportant. However, present samples cannot be used in the frequency because of scattering.
