Excerpt from The Electrical Transmission of PhotographsIN this small volume the Author has endeavoured to present in a simple and concise form the method of working of the various systems devised for the electrical transmission of photographs over metallic conductors, and although quite a lot of experimental work has been carried out in this direction during the last few years, to many, even those with electrical knowledge, the principles are somewhat shrouded in mystery.Although at present in a purely experimental stage, the science of photo-telegraphy is one that is rapidly growing in importance, and will, . When perfected, no doubt prove a necessary and valuable adjunct to existing telegraph systems.To those who are interested in original work, and who possess the necessary skill, a study of this subject will prove most interesting, Opening up as it does a large and as yet little explored field for original research, Short sections dealing with Television and the Wireless Transmission of Photographs have also been added, which will help the reader in becoming acquainted with the latest branches of photo-telegraphic work.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
