Abstract
A high-resolution phase contrast technique is applied for the measurement of an atmospheric-like artificial turbulence distribution along laser beam propagation path. This technique is based on a nonlinear Zernike wave front sensor that employs an optically addressed ferroelectric liquid crystal spatial light modulator. The measurements of dynamically changing phase distortions located at different distances from the wave front sensor were obtained. The spatial resolution, dynamic range, and time response of this technique are examined and compared with a theoretical analysis.
