成像系统关联成像压缩感知多光谱成像数字微镜器件 imaging system ghost imaging compressive sampling multi-spectral imaging digital micromirror device

摘要

将数字微镜器件（DMD）应用于压缩感知(CS)关联成像，在该成像方案中，只需用无空间分辨能力的桶探测器，并结合相应的算法就能得到物体的像；将此成像方案应用于多光谱成像，仅需用线列探测器就能得到物体多光谱像,简化了多光谱成像探测的光电记录过程。通过对关联成像和CS理论的介绍阐明了成像原理。在实验平台上搭建演示装置，分别用强度关联算法和CS算法计算得到物体像，通过比较表明CS算法提取信息的效率更高；且实验表明在透镜口径足够大时，成像系统的分辨率由DMD面元大小决定。在原成像装置上，对桶探测器接收的光强信号进行谱分辨测量，线列探测器记录各光谱信号,利用CS关联成像方法得到物体多光谱像。

Abstract

A digital micromirror device (DMD) is introduced to the ghost imaging via compressive sampling (CS). In this scheme, the image of object can be obtained using the bucket detector which has no spatial resolution. If the imaging scheme is applied to the multi-spectral imaging, multi-spectral images of object can be obtained using a linear array detector, which reduces the complexity of detector in imaging. The principle of ghost imaging is clarified with the correlated imaging the theory of CS. According to the imaging principle, the experimental demonstration device is assembled, and the object′s image is achieved accurately in the experiment. Ghost imaging and ghost imaging CS are compared to show that the latter has a better performance. Meanwhile, according to the experimental results, the resolution of the imaging system is decided by the size of unit on the DMD when the aperture of lens is big enough. Based on this imaging system, the multi-spectral imaging is carried out. The intensities at different wavelengths are recorded by the linear array detector, and the multi-spectral images of object are achieved in the experiment.
