A more expedient means of interpreting photographic distortion data via computerized digital analysis of the photo is also described. Finally, two new devices are introduced: one that measures angular deviation with extreme accuracy in a relatively small space and one that brings laboratory accuracy to field optical measurements. These latter devices employ state-of-the-art components and knowledge to provide extreme accuracy and usefulness. (Author) 收起
