Abstract : A study was conducted to develop a computer technique to analyze air-craft windshields for multiple imaging. Two types of multiple imaging were considered: internal reflection, or flare, and secondary reflec- tion. Emphasis was placed on secondary reflection multiple imaging. A CDC 6600 computer and FORTRAN were used throughout the study. A program was developed to evaluate multiple imaging in any windshield configuration reducible to a set of defining mathematical equations. Output is in the form of a matrix based on a spherical mapping. The matrix represents the pilot's effective view. The number of images the pilot will see is plotted for any given position of an object. If the conditions for internal reflection are present, a message will be printed. The program can then be altered to print a matrix map of the areas of concern. (Author, modified-PL)
