title: Checkerboard filters for gray-scale arrays.
abstract: A method of enhancing discrimination between adjacent channels in a binary coded array is described. A discussion is given of the application of this method to a photon counting system employing a static Gray-scale mask and to a system that employs a sequence of dynamically switched Gray-scale coded structures to produce a scanning electron beam.
