Examples of the multi-flash images that Prof. Moore used are in Hoppe's book. Here is an example:
A couple of other examples are in the book.
In the update to Prof. Moore's paper on the second page, he stated that his analysis was based on the assumption that the flash rate was constant for each scene. He later learned that Mili (the multi-flash photographer) adjusted the flash rate so it was faster when the ball was moving faster to get a better image to publish. Variable time scales are really hard to deal with.
The copy of Moore's paper above is from an original that I ran through an OCR program to extract and replace the text, which makes it searchable. The equations and tables are original. The program I used is FineReader by ABBYY.
