Researchers have designed a new digital streak camera that captures high-resolution images of projectiles travelling up to 3,350 m/s – 10 times the speed of sound.
The system was designed to replace the outdated film-based streak cameras , researchers said.
Film-based streak photography records the motion of an object as it passes in front of lens, while the film moves behind a vertical slit aperture during the exposure. The result is a long, continuous composite image of the object. However, the transition from film to digital has changed the photography industry, and the specialized film required for streak photography is no longer being manufactured.
