This paper reports a detection method of two-dimensional(2 D) enhancement and three-dimensional(3 D) reconstruction for subtle traces with reflectance transformation imaging, which can effectively locate the trace area of interest and extract the normal data of this area directly. In millimeter-and micron-scale traces, during 3 D construction, we presented a method of data screening, conversion, and amplification, which can successfully suppress noise, improve surface and edge quality,and enhance 3 D effect and contrast. The method not only captures 2 D and 3 D morphologies of traces clearly but also obtains the sizes of these traces.

In our Letter, two kinds of handwriting traces, colored and colorless, are studied by means of reflectance transformation imaging. The illumination direction and rendering mode can be changed alternatively to obtain two-dimensional and three-dimensional details of the traces that are not recognized easily by naked ***, an objective evaluation method without reference is applied to evaluate the reconstructed images,which provides a basis for setting the illumination direction and rendering mode. Therefore, the handwriting trace information including the written content, the writing features, and the stroke order features can be obtained objectively and accurately.

在28 nm及以下节点光刻机中,平顶高斯照明光场是减小脉冲量化误差对曝光剂量影响的关键技术之一。为降低平顶高斯照明光场产生组件的设计、加工和装调难度,提出一种光刻机照明光场强度分布校正技术。该技术通过较少次数的算法迭代可获得合适的光场校正板透过率分布,并将扫描方向强度分布的尺寸公差需求作为边界条件来降低校正引起的能量损失。所得到的光场校正板可同时对照明光场的非扫描方向积分均匀性和扫描方向光场强度分布进行校正。仿真分析结果表明,该技术获得的光场校正板可将照明光场的非扫描方向积分均匀性校正至0.29%以下,也可将扫描方向强度分布校正至指标范围内,校正引入的能量损失也可平均降低4.09%。所提技术可在一定程度上提高光刻机的产率。

Single layer lattice graphene deposited on the metal substrate can hardly be imaged by the optical microscope. In this Letter, a large field-of-view imaging ellipsometer is introduced to image single layer graphene which is deposited on a metal substrate. By adjusting the polarizer and the analyzer of imaging ellipsometer, the light reflected from surfaces of either single layer graphene or a Au film substrate can be extinguished, ***, single layer graphene can be imaged correspondingly under brightfield or darkfield imaging modes. The method can be applied to imaging large-area graphene on a metal substrate.
