A novel (to our knowledge) approach for resolution improvement in digital holography is presented in this paper. The proposed method is based on recording the incoming interference field on a complementary metal-oxide semiconductor (CMOS) camera with subpixel resolution. The method takes advantage of the small pixel size of the CMOS sensor, while overcoming the reduced fill factor. This paper describes the experimental and numerical procedures. The improvement of the obtainable optical resolution, image quality, and phase measurement accuracy are demonstrated within this paper.
本文提出了一种（据我们所知）用于提高数字全息分辨率的新颖方法。所提出的方法基于使用具有亚像素分辨率的互补金属氧化物半导体（CMOS）相机记录入射干涉场。该方法利用了CMOS传感器的小像素尺寸，同时克服了填充因子降低的问题。本文描述了实验和数值过程。本文展示了可获得的光学分辨率、图像质量和相位测量精度的提高。
