光学成像是人类获取信息的最重要手段,传统成像方法难以克服光在传播过程中遇到的散射干扰,当天文望远、生物显微、医学成像甚至日常生活观察等众多场合遇到散射影响时无法获得高质量的图像。如何在存在散射影响的情况下实现光学成像是人们长久以来渴望解决的基本光学问题之一。随着科技的发展,对这一问题的研究取得了不少突破。文章对这些突破和进展进行了讨论,并重点介绍了利用光场调控和解卷积成像技术实现透过散射体成像恢复的研究进展。
Optical imaging is an important means for mankind to acquire information.However, in the presence of scattering it is difficult to obtain good quality images by conventional imaging methods, for example, in astronomy, bio-medical microscopy, and even daily observation. This is not only a fundamental optics issue but also a long-standing problem that has yet to be solved. Thanks to the development of science and technology, great breakthroughs have been made in recent years. In this letter, the latest progress in the technique of imaging through scattering media by light field modulation and de-convolution methods is described and discussed.
