Pattern Threshold Recognition Device.

Abstract

The report details effort directed toward development of a Pattern-Recognition Device. This vacuum-tube consists of an image-converter input, a storage-target which can be switched over the secondary-emission first-crossover potential in areas of intense signal, a flood-gun to suppress background information, and a read-gun to provide an electrical output of the stored information. The report discusses four main tasks which culminated in the Pattern-Recognition Device. The task of target-development includes fabrication techniques, an analysis of target-operation and the results of target-evaluation. The task to develop an image-converter input and a flood-gun collimation-system are presented. The task to design a suitable read-gun is discussed, and finally the results obtained on the final-design tubes are presented. (Author)
