Ag Nanoparticles: Experimental Study of Sign Identification of Nonlinear Refractive Index by Moiré Deflectometry and Z-Scan Methods
Figure 7
(a) The experimental setup for , , (b) deflection of Moiré pattern; the red dashed lines show the movement of the grating vector image, in which is grating, L is lens, and and are the pitches of grating and Moiré fringes, respectively.
