The Role of the Slit-Scan Image in Science and Art
The use of slit-scan photography is actually quite old. It is often called line-scan, photo finish, or streak photography. Slit-scan photography has a rich and colorful history rooted in chemical analog photography. This technique is often used to visualize high-speed events such as missiles and bullets, although it is probably best known as photo finish photography used to determine the outcome of races.
