Rectification of Multiflash Radiographs
Abstract
This short paper is intended for use in a comprehensive course in ballistic flash radiography for technicians, engineers, and scientists. This paper presumes that the reader knows what a flash radiograph is and has seen a number of multi-flash radiographs and understands the geometric concepts underlying the setup used to create them. Some knowledge of the terminology of geometric optics is helpful but not necessary, as is some experience with terminal ballistic testing (due to the nature of the examples). The paper does not use any complicated mathematics. It is practically oriented, giving some non-numerical examples and some helpful suggestions. After reading the paper, one should be able to graphically determine the true position of an object in space from the positions of its images on properly made multiflash radiographs. This paper has not been used in connection with a radiography course prior to its publication. The techniques discussed in this paper are equally applicable to any multiple image stereographic projection for which the projection factors can be calculated for the image of each feature of interest.
