Abstract
A special presentation will be made to describe the Viking Ground Reconstruction Equipment (GRE) which was designed to compliment the Viking facsimile camera. Together the camera and the GRE make up the Viking Imaging System. The GRE is a computer controlled laser beam recorder that uses a spinning scanning mechanism to write picture information onto film. The geometric accuracy of the GRE is ten (10) times better than the camera. The equipment can produce high resolution black and white negatives, composite color negatives, color separation negatives, and quick look Poloroid pictures, both in color and black and white. For high resolution black and white photographs the GRE is capable of generating sixty-four (64) density levels on film in a linear or logarithmic fashion. The presentation will describe the design requirements of the GRE, the technical implementation, and show some photographs taken by a Viking camera and reproduced on the GRE.
