摘　　要：基于连续扫描的太赫兹成像系统可以应用在探测煤层裂隙领域,由于煤层内部的裂隙对太赫兹波有不同的吸收,因此反映到太赫兹图像上为灰度值的不同,从而判定煤层内对应裂隙的位置和深浅信息。利用连续太赫兹波的反射扫描成像系统对煤块进行成像实验,并且通过一些算法获得高分辨率的图像,最后对这些算法进行比较和分析。Terahertz continuous scanning imaging system can be used in the detection of coal seam cracks. According to the difference of the absorption intensity of the coal seam cracks, the different gray values in the image can be inapped. So it can detect the location and depth of the cracks in the coal seam. The imaging experiment of coal seam cracks was accomplished by using the terahertz continuous scanning imaging system. And the high resolution image was obtained by some algorithms that would be compared and analyzed in the end.
