Add a one-line explanation of what this file represents


English: A green laser beam passes through an irregular sheet of glass and produces an image on the wall. Here the caustic effect, normally seen with incoherent light, is combined with interference of laser rays travelling along different lenght paths because of varying refraction angles. Class III laser pointer, 530nm lambda, 0.05m laser to glass distance, 3m glass to wall distance.
Français : Image produite sur un mur par un faisceau laser vert ayant traversé une feuille de verre irrégulière ; ici l'effet habituellement observé avec une lumière incohérente s'est combiné à l'interférence des rayons laser qui se déplacent le long de trajets de longueur différente à cause des angles de réfraction variables. Données : Pointeur laser de classe III, lambda 530nm ; distance laser-verre 0,05m ; distance verre-mur : 3m
