Paper Abstract

The problem of determining the quality of an image produced by a line-scanning system received increased attention in the early 1960's with the advent of low-light-level television and infrared imaging systems for military aircraft. In addition, the interest in manned lunar exploration, with the attendant need for better evaluation of the lunar surface, made necessary the telemetering of image data by such systems as Lunar Orbiter and Surveyor. An understanding of image quality became more critical once it was realized that digitizing of the video signal for transmission introduced a different form of noise (the so-called "striping") into the video signal. As a result of these several more-or-less simultaneous needs, research into the nature of line-scan image quality and its effect upon image interpretability was begun about 1961, and has continued through the present.
