Paper Abstract

The 3M Brand EBR-700 series Electron. Beam Image Recorder has been developed to produce corrected 50mm images on 70mm film of data from the camera systems aboard the ERTS A spacecraft. The images are produced by raster scanning with direct electron beam bombardment on film. The machines are capable of producing high quality 70mm black and white film from monochrome video signals. The resolution, (in excess of 6000 TV lines), dynamic range (in excess of 100 to 1), geometric accuracy,. and sensiometric fidelity provide a near-transparent window through which the outputs of the Return Beam Vidicon and Multispectral Scanner camera systems can be displayed.
