横向反卷积在超声检测中的应用

Application of Lateral Deconvolution in Ultrasonic Testing

本文叙述了反卷积的基本原理。并结合复合材料粘结质量的检测,给出了具有两个控制参数的反卷积核。选择该参数,可得到噪声低、分辨率较高的结果,从而可提高检测精度。

In this paper the basic principle of the deconvolution is described. In order to improve the quality of detecting the adhesive of complex materials, the deconvolution is used. By an empirical approach, the kernel of the deeonvolution with two controlled parameters is given. With these parameters chosen, the noise can be controlled and the lateral resolution is enhanced, thus it is easier to detect the details of adhesive and defects.
