为了改善高温超导SQUID显微镜的高分辨率磁像，我们利用MATLAB数值分析程序开发了一种后滤波技术。SQUID具有在室温下在空气中突出到样品的高磁导率通量引导件。与硬件滤波器相比，软件滤波具有可以自由选择分析对象的优点。通过后滤波处理，获得了高分辨率的磁性图像，可以分辨出几个微米级磁性颗粒的磁性微结构。它只花了38秒的情况下，我们的PC与2GHz的处理器.
We have developed a post filtering technique by the numerical analysis program in MATLAB to improve the high-resolution magnetic image of an HTS scanning SQUID microscope. The SQUID has a high-permeability flux guide protruded to a sample in air at room temperature. Software filtering has an advantage that an object to analyze can be freely selected in comparison with hardware filters. The magnetic image of such a high-resolution as we can discriminate the magnetic microstructure of a few micron-size magnetic particles was obtained by means of our post filtering processing. It took only 38 seconds in case of our PC with a 2GHz processor.
