Andrew Davidhazy is an academic who works at RIT in the US. He has written a lot abou the mechanics of both strip photography used in finishing line imagery as well as slit scan images caused by slowly exposed slits panning the image plane. I have read his texts for technical information, although I don’t see the need to repeat them here. Below is on of his personal images as well as links to his texts online.
