Abstract

A method that is to stabilize holographic interference fringe during holographic recording process is put forward in this paper. As the kernel of this method, a negative feedback system based on linear CCD and piezoelectric ceramics (PZT) which is used to compensate the interference fringe random drift caused by various external vibrations in long time recording process was introduced in details. The proportion-integral-derivative method (PID) is adopted to control the moving of PZT which is used to compensate the drift of the interference fringes accurately. Thus the interference fringe can be frozen. Experiment results shows that this negative feedback system by controlling the optical path difference can effectively compensate the interference fringe random drift caused by various external vibrations in long time recording process. After using this system, the mean squared error of the interference fringe drift value can be under λ / 60 and the quality of the holographic grating is improved greatly.
