Abstract: A machine is described which was developed at Bell Laboratories at Holmdel, N.J., in connection with the PICTUREPHONE® program to provide high resolution graphics transmission capability. This particular machine was designed using commercially available components. A low-power, 10-mW, continuous-wave helium cadmium laser is used to scan simultaneously an 8½- by 11-in (21½- by 28-cm) page original and a 24 × reduced image on vesicular diazo heat developable film. A 1400-picture element by 2000–line image, with full gray scale, is transmitted over a 0.5-MHz line in 4 seconds, and developed in less than one second. Each machine is a transmitter-receiver capable of local copy. Applications, operating modes and results are presented.
