Talbot-Effect using a 666nm laser, a grating (comb) with 1mm period and a f=200mm cylinder lens.
Possibility 1: As shown in drawing, L = 1.5mm, d = 1mm, f = +-200mm (+-5 dpt.)

Possibility 2: Single concave lens f=-200mm, the comb is placed right between focal point of lens and the wall: focal point-3m-comb-3m-wall.
Deutsch: Nahfeld-Interferenzmuster durch

Möglichkeit 1 (gezeichnet): L = 1,5m, d=1mm, f=+-200mm (+-5 dpt.)

Möglichkeit 2: Nur eine koncave Linse f=-200mm: Der Kamm steht genau zwischen Brennpunkt der Linse und Wand: Linse-3m-Kamm-3m-Wand.
