Abstract: THE principal element of the Scophony Laboratories (London, England) system of television is described in a recent paper.∗ The Scophony system, using entirely optical methods, has set the pace for large-screen television in England. The method employed can produce high-quality pictures up to 15 feet wide as well as 18- and 24-inch domestic pictures.
