Auf dem Bild sieht man die Anwendung mit einer Petrischale, deren Hälften man zueinander verdrehen kann, um nur das Licht einzufangen, welches das Objekt durchlaufen hat; im Beispiel sind Fasern eines Taschentuchs zu sehen, ebenfalls ein Vergleichsbild mit normalem Licht. Wenig Aufwand, große Wirkung.
