(Music) [A laser pulse is fired] (Music) 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.
(Musique) Nous allons tirer ces balles de lumière, qui vont heurter ce mur, et parce que le paquet de photons, se dispersera dans toutes les directions, et certains atteindront le mannequin caché, qui à son tour dispersera la lumière, et à nouveau la porte renverra une partie de cette lumière dispersée,
