摘要
太赫兹双轴反射式共焦扫描成像技术可穿透非极性非金属材料并实现高分辨三维成像,因此具有广泛的研究和应用价值;其二维成像质量与物体轴向位置有很大关系。利用2.52THz双轴反射式共焦扫描成像系统进行了物体轴向位置对二维成像质量的影响实验。引入线对比度和区域对比度客观描述成像质量,主客观评价基本吻合。
Terahertz dual-axis reflection confocal scanning materials and then realizes high-resolution 3D imaging imaging technique can penetrate nonpolar and non-metallic thus it has wide research and application values. Its 2D imaging quality is greatly related to the axial position of the object. Experiments about the influence of the object axial position on the 2D imaging quality are carried out by utilizing 2.52 THz dual-axis reflection confocal scanning imaging system. Line contrast and area contrast are introduced to objectively evaluate the imaging quality. The subjective evaluation tallies with the objective evaluation basically.
