The setup uses a G0 grating as source grating, a phase grating (G1) at distance l = 5.23 m and an analyser grating G2 at distance dt3 from G1. With a dt3 that resembles the third talbot distance (5.7 cm) we could place the sample between G1 and G2 and vary the distance L between sample and G2. cg indicates the concentration gradient in solution of sedimented particles.
