传统的成像系统由于需要凸透镜等镜头元件,成像系统的厚度和成本较大。为了使成像系统变得更加紧凑、成本低,无透镜成像系统迅速发展,例如无透镜显微镜。利用偏振片采集偏振信息,并利用双面透明胶带替代凸透镜,结合计算成像技术,构建了一个无透镜偏振计算成像系统。系统地介绍了该系统,并通过实验证明该系统可以实现拍照功能,采集到的偏振图像符合马吕斯偏振定律。基于散射元件的无透镜偏振成像系统可以有效地减小相机的厚度和成本,并且可用于偏振图像的采集场合。

Conventional imaging systems have large thickness and high operating cost because of requiring lenses such as convex lenses. To make imaging systems with lower operating cost and better compactness, lensless imaging systems have developed rapidly, such as lensless microscopes. Here, a polarizer is used to achieve polarization information and double-sided transparent tape instead of convex lenses is used to collect object morphologic information. A lensless polarization computed imaging system is constructed and described in detail by combining computational imaging technique. The system is introduced systematically. Its functionality as a camera is demonstrated experimentally; the acquired polarized images comply with the Marius polarization law. The lensless polarization imaging system based on scattering components can reduce the camera thickness and cost, and can be applied to acquisition of polarized images.
