Albert Rose
Encyclopedia
Albert Rose was an American physicist, who made major contributions to TV video camera tube
s such as the orthicon, image orthicon, and vidicon.
He received an A.B. degree and a Ph.D. degree in Physics from Cornell University
in 1931 and 1935, respectively. He joined RCA
, where was active in the development of TV camera tubes.
He was known to be an expert on photoconductivity
. For example, he wrote a book "Concepts in photoconductivity and allied problems", which was published by John Wiley & Sons, New York in 1963. He also did research on the visibility of objects in a noisy signal (TV-tubes). He measured that objects could be detected for 100% if the object visibility was 5 or higher Rose Criterion. He is also known to be at the origin of the Detective Quantum Efficiency (DQE) concept, today widely used in optical and X-ray imaging.
He died in 1990.
Video camera tube
In older video cameras, before the mid to late 1980s, a video camera tube or pickup tube was used instead of a charge-coupled device for converting an optical image into an electrical signal. Several types were in use from the 1930s to the 1980s...

Photoconductivity
Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation....
