Leonard L. Sokolov

Leonard L. Sokolow (born June 13, 1920 in Kern County , California , United States , † November 1984 in California) was an American inventor and Oscar winner in the field of technical merit.

Life

Sokolow grew up in California, where he also received his education. He was active in the field of technical development and invention, his patent applications have been handed down. His greatest success was achieved in collaboration with colleagues Edward H. Reichard and Carl W. Hauge with the development of so-called xenon flash tubes as light sources. In a trade journal it said: “The Cinex Exposure Tester has been widely used for many years to make timing tests from black and white negatives. By replacing the incandescent lamp normally found in this tester with a xenon flash tube and its capacitor discharge power supply, the resulting stable and reproducible light output has enabled the development of a superior testing machine. The exposure gate has been modified to include a series of neutral density steps that match the press lights. For subtractive color tests, a selected range of color filters is added to the neutral density. The resulting intensity tests closely match the press exposure times, which solves the differences in film thickness recoil force normally found in Cinex tests. " For this achievement, all three received the technology Oscar in 1965, "for the design of a proximity cue detector and its application to motion picture printers".
