Abstract : This report describes the technical work accomplished in the third phase of a program to develop an automated, three-dimensional, quantitative surface topography measurement system using a stereo-pair of scanning electron microscope (SEM) micrographs. The first phase of the program explored the technical feasibility of making quantitative three-dimensional measurements of surface topography using a stereo-pair of SEM micrographs. In the second phase of the program the hardware and the software necessary to implement the surface topography measurement system were developed and the integrated system was tested to verify its performance. The objectives of the third phase of the program were to provide a data display capability for the system and to refine the system to improve its performance. The hardware and software procured for the data display capability is described in Section 2. The statistical software module for the computation of physical surface features is described in Section 3. Graphics display software to draw surface profiles and contour maps is described in Section 4. Section 5 describes the additional work done in Phase III. The technical status of the program and suggestions for further work are presented in Section 6.
