Incredible. From Neatorama:
Germany’s Werner Mehl is the talented engineer who created the PVM-21 infrared chronograph, in many respects the most sophisticated ballistic speed-measuring system currently available to the general public. Werner runs a company, Kurzzeitmesstechnik, which specializes in high-tech ballistic measuring systems and ultra-high-speed photography. Werner has engineered camera and lighting systems that can literally track a bullet in flight, millimeter by millimeter, with eye-popping resolution. Werner employs digital cameras that record up to 1 million frames per second, with effective shutter speeds as fast as 1.5 nano-seconds. The videos produced by Werner’s systems are amazing. Below are two short samples. The first shows a 7mm bullet penetrating cardboard. Note you can clearly see the engraving of the rifling on the bullet.
I really like finding out about professional in-jokes.
