The method based on frequency-wavenumber domain filtering has great potential in suppressing the incident wave. However, the inspection error can′t be avoided, the noise in reflection wave fileld got by this method is so much. High-resolution laser ultrasonic testing is used to realize the wavefield visualization in the aluminum plate. Adjacent waves subtraction after arrival time matching and the frequency-wavenumber domain filtering are both used in this paper to weaken the incident wave. The results show that the proposed filtering method has a good performance in improving the visibility of the damage-reflected wave, and the included noise is less.
