La cámara rapatrónica (ensenado.blogspot.com)
Esta tecnología permitió tomar fotos de explosiones atómicas y se lograron descubrir muchos detalles no imaginados. Como por ejemplo que el “envasado” de la bomba logra alterar la regularidad de la “bola de fuego”; o que gran parte del calor se proyecta más rápidamente hacia los objetos inmediatamente cercanos -como permitió comprobar el “efecto cuerda”, picos que se forman bajo la bola quemarse los cables que sostienen la estructura de la bomba-.
Rapatronic camera (Wikipedia):
To overcome the speed limitation of a conventional camera's mechanical shutter, the rapatronic camera uses two polarizing filters and a Kerr cell. The two filters are mounted with their polarization angles at 90° to each other, to block all incoming light. The Kerr cell between the filters, which changes the polarization of light passing through it when energized, acts as shutter when it is energized at the right time for a very short amount of time, allowing the film to be properly exposed.

THE MARMALADE Identity: Behind the scenes (Super Slow Motion Effects That Look CGI)
Published on 12 Jun 2012 by TheCGBro
The Marmalade, a special effects studio in Germany, has created an incredible high speed robot used to film precise moments during ultra high frame rate takes. The results look so perfect it looks like CGI!! Thanks to Sunstar at Death Fall for the tip!
Check out more of their awesome work on their website:
