Cartographic Electron Beam Recorder (EBR) System.

Abstract

This report describes the development of an advanced model of a Cartographic EBR for use in plotting and recording a variety of map and image data on electron sensitive film. Performance levels achieved with the minicomputer controlled EBR are satisfactory for the automated production of a number of cartographic products. Recording spot sizes of 3 and 6 microns diameter; beam addressability of 32,000 x 32,000; image repeatability of 1/30,000; and geometric fidelity of 0.03% have been demonstrated. Image format sizes were 5 inch x 8 inch, 4 inch x 6 inch, 70 mm and 35 mm. 32 line widths can be varied automatically from 6 to 250 micrometer. Graphic arts quality characters can be recorded from 4 pts to 36 pts (at full scale). (Author)
