Ramesh Raskar: We're going to fire those bullets of light, and they're going to hit this wall, and because of the packet of the photons, they will scatter in all the directions, and some of them will reach our hidden mannequin, which in turn will again scatter that light, and again in turn, the door will reflect some of that scattered light. And a tiny fraction of the photons will actually come back to the camera, but most interestingly, they will all arrive at a slightly different time slot. (Music)
Dispararemos esas balas de luz, que impactarán en esta pared, y debido al paquete de fotones se esparcirán en todas direcciones, y algunas alcanzarán al maniquí oculto que a su vez dispersará esa luz y nuevamente la puerta reflejará parte de esa luz dispersada, y una fracción pequeña de los fotones regresará a la cámara pero, curiosamente, en momentos levemente diferentes.
