标题： Application of image processing in optical method, Moire deflectometry for investigating the optical properties of zinc oxide nanoparticle

摘要： 如今，测量纳米材料的折射率通常使用光谱光度法和机械方法，这些方法成本高且间接。 在本文中，为了测量氧化锌纳米材料的这些参数，使用了两种不同的稳定剂，采用了一种简单的光学方法——莫尔偏折法，该方法基于波前分析和几何光学。 在莫尔偏折法中，激光二极管的光束通过样品。 结果，观察到样品环境的变化表现为条纹的偏转。 通过使用CCD记录这些偏转并用MATLAB进行图像处理，可以计算出纳米材料的折射率。 由于该方法的高精度以及在Matlab中改进的图像处理代码，可以测量样品中折射率的最小变化。 数字图像处理用于以选择特征并显示的方式处理图像。 这种方法得到的结果显示出对其他使用方法的良好改进。 显示英文摘要

摘要： Nowadays for measurement of refractive index of nanomaterials usually spectro-photometric and mechanical methods are used which are expensive and indirect. In this paper for measuring these parameters of zinc oxide nanomaterial with two different stabilizers, a simple optical method, Moire deflectometry, which is based on wave front analysis and geometric optics is used. In the Moire deflectometry method, the beam of light from the laser diode passes through the sample. As a result of that, a change in the sample environment is observed as deflections of the fringes. By recording of these deflections using CCD and image processing with MATLAB, the nanomaterials refractive indices can be calculated. Due to the high accuracy of this method and improved the image processing code in Matlab, the smallest changes of the refractive index in the sample can be measured. Digital Image processing is used for processing images in a way that features can be selected and being shown. The results obtained in this method show a good improvement over the other used methods.
