利用散射介质同时改善多个成像参数
Simultaneously improving multiple imaging parameters with scattering media
摘要：
传统的光学成像系统通过消除像差可以提供具有复杂和昂贵的光学设计的高质量成像。利用光学记忆效应，首次提出了通过在成像系统中加入散射介质，不是单独改善单个成像参数，而是同时改善多个成像参数。以一个简单的单镜头成像系统为例，通过在镜头和摄像机之间放置散射介质，除了大大提高了景深外，还同时消除了球差、彗差和色差。结果表明，散射介质在光学成像、光学测量和生物医学等领域具有潜在的应用价值。
英文摘要：
Traditional optical imaging systems can provide high-quality imaging with complicated and expensive optical design by eliminating aberrations. With the help of optical memory effect (ME), not independently improving single imaging parameter, but simultaneously improving several imaging parameters by adding scattering media to the imaging systems was demonstrated firstly. As an example, in a simple single-lens imaging system, except the depth-of-field (DOF) was improved greatly, spherical aberration, coma aberration and chromatic aberration were eliminated simultaneously by placing a scattering medium between the lens and the camera. The results indicate the potential applications of scattering media in many fields such as optical imaging, optical measurements and biomedical applications.
