Abstract

Movement of optical patterns due to a slight lateral shift of wave-front in the nonlinear optical feedback system is investigated experimentally and theoretically. The dependence of the speed of patterns on the lateral shift is demonstrated experimentally and estimated by using the linear stability analysis. A small angle measurement using the nonlinear optical feedback system is discussed.
