Rapatronic Camera: An Atomic Blast Shot at 1/100,000,000th of a Second

atomic2

This is a photo of an atomic bomb milliseconds after detonation, shot by Harold ‘Doc’ Edgerton in 1952 through his Rapatronic (Rapid Action Electronic) Camera.

The photo was shot at night through a 10 foot lens, situated 7 miles away from the blast, atop a 75 foot tower. Edgerton systematically turned on and off magnetic fields acting as the camera’s shutter, as opposed to a conventional, mechanical close.

How fast was the magnetic field shutter? 1/100,000,000th of a second. Read more…

Photo of a Nuclear Explosion Less than 1 Millisecond After Detonation

This might look like some kind of microscopic organism, but it’s actually a high-speed photograph of a nuclear explosion. It was captured less than 1 millisecond after the detonation using a rapatronic camera, which is capable of exposure times as brief as 10 nanoseconds (one nanosecond is one billionth of a second). The photograph was shot from roughly 7 miles away during the Tumbler-Snapper tests in Nevada (1952). The fireball is roughly 20 meters in diameter, and three times hotter than the surface of the sun.
