Albert Rose (physicist)

Albert Rose (born March 30, 1910 in New York City , † July 26, 1990 ) was an American physicist. He is known for developments in the field of image pickup tubes for television and video, and for image recognition under noise.

Rose studied physics at Cornell University with a bachelor's degree in 1931 and a doctorate in 1935. He then went to RCA , where he developed picture tubes for television cameras (Orthikon, Image-Orthikon, later Videocon). The Orthicon was developed by him and his colleagues in 1937 and was used for television recordings at the World Exhibition in New York in 1939. From 1942 he developed the Image Orthicon with Harold Law and Paul K. Weimer at the newly founded RCA Laboratories in Princeton. During the Second World War it was used by the US Navy for rocket guidance experiments, and after the Second World War it was the basis of television cameras worldwide for twenty years. 1955 to 1957 he headed the newly founded RCA laboratories in Zurich. In 1975 he retired from RCA, but continued to work as a consultant.

He examined the recognizability of television images and, in general, of images with a noise component. He found out that people could still reliably identify individual picture elements if their signal-to-noise ratio was at least 5 ( Rose criterion ). He also introduced the concept of Detective Quantum Efficiency (DQE) for image recording devices under the influence of noise.

In 1979 he received the IEEE Edison Medal and he received the IEEE Morris N. Liebmann Memorial Award . He was a fellow of the IEEE and the American Physical Society . In 1959 he became a fellow at RCA. In 1958 he received the RCA David Sarnoff Outstanding Achievement Award in Science and Engineering and the David Sarnoff Gold Medal Award from the Society of Motion Picture and Television Engineers.

He held over 40 US patents.
