Summary[edit]

Description
English: Near-field interference pattern created by the talbot-effect

using white light (halogen lamp) and a self-made phase grating. G0 absorption grating right before lamp has same period as phase grating. Phase grating is build by cutting slits into a plastic foils.

The foil is put between parallel glass plates into lineseed oil (nearly same refraction index).
Deutsch: Nahfeld-Interferenzmuster erzeugt mit dem Talbot-Effekt

mit weißen Licht (Halogenlampe) und einem Selbstbau-Phasengitter. Der Kamm (Absprotionsgitter) direkt vor der Lampe hat dieselbe Periode wie das Phasengitter. Das Phasengitter ist gebaut indem Schlitze in eine Plastikfolie geschnitten wurden. Die Plastikfolie kommt zwischen zwei Glasscheiben in Leinöl das einen ähnlichen Brechungsindex hat.

Der Unterscheid der Brechungsindizes ist grob geschätzt 0,01.
