%X The algorithm and principle of the adaptive filter as well as its application as a noise cancellation wave trap are analyzed in face of the noise disturbance from acoustic optic modulation and electric optic modulation. A reasonable structure of the wave trap is proposed in time domain and the result of its computer simulation is given. Because all the procedure can be done without the detailed model about the LDV system, it is rather simple and practical. Experiment results show the effectiveness of the method proposed.
