Electroprinting tubes and their applications to television facsimile |
| |
Abstract: | This paper describes two types of electroprinting tubes, one of which has been applied to television facsimile. The electrostatic printing tube and fiber-optics printing tube have a resolution of 8 lines/mm and 15 lines/mm, and a writing speed of 200 m/s and 1700 m/s, respectively. The electron scanning method utilizing the fiber-optics printing tube showed good results in experimental television facsimile. |
