摘要
在对散射介质散射特性进行分析的基础上,提出了一种对散射介质中物体进行单像素成像的方法,基于数字微镜阵列和单点探测器,设计并搭建了相应的单像素成像系统。通过对数字微镜阵列加载一系列具有不同相位的条纹图案,采集对应的光强信息,结合图像恢复算法,实现了对位于散射介质中的物体成像。为了去除噪声,分析了噪声的来源,设计了滤波器对所拍摄的物体图像进行滤波处理,图像质量得到了显著提高。与传统散射介质成像系统相比,该系统结构简单,无需复杂的标定过程,在多个领域具有应用前景。
Abstract
On the basis of the analysis of scattering media scattering characteristics, a single pixel imaging method is proposed to capture the image of the objects in scattering media. Based on the digital micro mirror array and a single point detector, the corresponding single-pixel imaging system is designed and built. Series of stripe patterns with different phases are loaded on the digital micro mirror array and the intensity informations are recorded by the detector. Then the image restoration algorithm is used to get the reconstructed image of the objects in the scattering media. In order to remove the noise, the source of noise is analyzed, a filter is designed for filtering, and the image quality is significantly improved. Compared with the traditional scattering medium imaging systems, this system is simple and without complex calibration process, so it can apply to many fields.
