Summary[edit]

Description
English: Near-field interference pattern generated by

Talbot-Effect using a halogen lamp (slide projector), a "G0" grating (comb) with 2mm period, a "G1" grating (comb) with 1mm period, and a "G2" printed bar pattern with 1.8mm period. Distances: slide projector (lamp) - 10cm - G0 - 3m - G1 - 3m - paper "G2".

Design wavelength is 666nm (red) which is bad for contrast but good for colors.
Deutsch: Nahfeld-Interferenzmuster erzeugt durch den

Talbot-Effekt mit einem Diaprojektor (Halogenlampe), einem "G0" Gitter (ein Kamm) mit 2mm Periode, einem "G1" Gitter (ein Kamm) mit 1mm Periode, einem "G2" gedrucktem Balkenmuster mit 1,8mm Periode. Abstände: Diaprojektor (Lampe) - 10cm - G0 - 3m - G1 - 3m - Papier "G2".

Ausgelegt auf 666nm (Rot) - das gibt starke Farben aber wenig Kontrast.
