Parallel Optical Processing to Convert Elevation Data to Slope Maps. Phase II. Practical Considerations.

Abstract

The considerations in designing and calibrating a coherent optical data processing system for quantitative slope computation from a transparency with amplitude transmittances as a function of surface terrain elevations are described in this report. Methods of designing the spatial filter and criteria for selecting the optical system components to minimize the errors in determining slopes are described. Procedures for calibrating the input transparency and the optical system are specified. (Author)
