Abstract: An image transmission system is disclosed in which the image is obtained from a reduced size medium such as microfilm. A scanning beam is incident upon a first reflector which causes the beam to be redirected onto a second reflector fixedly spaced therefrom. The second reflector in turn redirects the scanning beam onto the film. By moving the two reflectors with respect to the source of the scanning beam by a relatively large distance, the scanning beam is moved by a much smaller distance over the plane of the film, to permit scanning over a new line on the film.
