Abstract
In the course of evolving a completely new news picture distribution system for the Associated Press, we have developed a facsimile system using laser scanners and dry silver paper. It is believed that a substantial improvement in cost/performance ratio has been achieved. The system features feedback intensity control of a modulatable He-Ne laser, a flat-bed double pass optical system, a galvanometer-driven mirror for horizontal scanning, paper motion for vertical scanning, and oven pro-cessing of the exposed paper. The tone scale is controlled with stable processing conditions and a non-linear amplifier to compensate for the D log E characteristic.
