The annular cavity photorefractive oscillator is a typical nonlinear optical system, under the condition of certain parameters show the nonlinear characteristics of bifurcation and chaos. This paper USES the constant migration method to realize circular cavity of spatiotemporal chaos control in the photorefractive oscilator.%光折变振荡器是典型的非线性光学系统,在一定的参数条件下表现出分岔与混沌等非线性特征.本文利用常数偏移法实现在环形腔光折变振荡器中的时空混沌控制.
