摘要
随着科学技术的发展,针对不同物体不同偏振特性的应用越来越多。现有的偏振研究成果多是建立在灰度图像的基础上,关于彩色图像偏振问题的研究相对较少,其难点主要集中在获取圆偏振态时需要根据不同波长的光搭建不同的光路。针对这一难题,提出了一种基于数字微镜器件的彩色图像偏振态获取方法,利用计算机图像生成器对图像进行彩色分解形成RGB三色图像,然后通过三块DMD分别对三种颜色的图像进行投放,经由光学系统最后生成含有偏振态的彩色图像,可以大大提高图像的辨识度。
With the development of science and technology,more and more applications of different polarization characteristics have been applied to different objects. The existing research results of multi polarization is established on the basis of grayscale image,the research of color image is relatively few,and the difficulties are mainly focused on the construction of different optical paths according to different wavelengths of light. To solve this problem,a method for obtaining polarization states of color images based on digital micromirror devices is proposed,the color of image is decomposed into RGB color image using computer image generator,and then the images of three colors are put into the image by three blocks of DMD,and the color images with polarization states are finally generated through the optical system,which can greatly improve the recognition of the image.
