About This Book

This work discusses the early innovations in transmitting images via radio, highlighting the patent by Nipkow in 1884, which proposed a system using a selenium cell and a rotating perforated disc to capture scenes. It also examines the contributions of Shelford Bidwell, who earlier described a method for telegraphic transmission of images. The text details the technological advancements in the field, including the use of polarizing light valves for image reception, and provides insight into the author's background as an inventor and pioneer in motion picture technology and radio photography.
