Abstract

In order to obtain the two dimensional distribution of the refractive index changes due to the domain inversion in the RuO₂:LiNbO₃ crystal, we make use of the Mach-Zehnder interferometer system to record holograms, with the object light transmitting through the poling RuO₂:LiNbO₃ crystal, and then filter the spectrum in the frequency domain to get the object light spectrum for numerically reconstructing the object wavefront. The results confirm that the electro-chromic effect region well agrees with the domain inversion region in RuO₂:LiNbO₃ crystal.
