Slow Dance - Un gadget qui ralenti visuellement le temps

HOW IS THIS POSSIBLE?

Strobe lights are nothing new. From the photos of Edwaerd Muybridge to the photos of Doc Edgerton, extremely fast strobe lights have been helping us to see into fast motions. On a dancefloor, strobe lights turn us into stop motion animations. But we’ve put strobe light to use in a different fashion.

By using high speed strobe lights blinking 80 times a second, your eyes cannot even see that they are blinking — the light looks continuous. By synchronizing the strobes to the high-speed vibration of objects (feathers, branches, flowers, etc), we create the visual illusion of those objects moving in slow motion. This is a phenomenon called persistence of vision, and works similarly to the way a TV works — by flickering frozen images quickly enough that we perceive them as continuous motion.

C'est probablement comme quand on voit les hélices d'hélicoptère tourner lentement ou devenir fixes quand on les filme. Il "suffit" de ne laisser voir que des images courtes pendant la vibration avec un tout petit décalage dans le temps à chaque fois.
