In this study, a new method for measuring the nonlinear refractive index of materials using the moir e deflectometry is reported. We describe the experimental details and present theoretical analysis for obtaining the magnitude and the sign of nonlinear refractive index of materials, n 2 , using the
In this paper, we proposed a phase shifting Lau phase interferometry for the measurement of the focal length of a lens. The fundamentals of this application are discussed and the basis of the phase map interpretation is outlined. A three step phase-shifting algorithm is used to depict the phase maps
