Very interesting. It's the precursor to the drum scanner.

Very cool. Same principle used on movie film to make sound using Photosensitive tubes in projectors.

It's the precursor to the drum scanner.

Which were in use by the end of the 1940s.

I read somewhere (decades ago) the famous photograph of the Hindenburg disaster was sent over Atlantic by telephone cable, now I know how! Fascinating.
