摘要
单像素成像为突破经典成像中像素数量的限制提供了方法,但要实现良好稳定性和准确性的相位成像仍然是一个挑战.基于现有的单像素成像框架,提出了一种无需干涉测量与相位迭代算法的单像素相位成像方法.通过傅里叶频谱零级强度测量发现,该方法实现了相位成像.实验结果表明,相位成像的重复精度为0.12％,误差为4.1％,证明了该方法具有良好的稳定性和准确性,对单像素成像的进一步发展和经典相位成像的突破创新均具有一定的借鉴意义.
Abstract
Single-pixel imaging offers a means of overcoming the constraints imposed by the limited number of pixels in conventional imaging.The realization of phase imaging in a single-pixel framework with consistent stability and optimal accuracy remains challenging.In this study,we propose single-pixel phase imaging without interferometry and a phase iteration algorithm.The proposed methodology relies on extracting the zero-order intensity of the Fourier spectrum and experimentally achieves a repetition accuracy and error rate of 0.12％and 4.1％,respectively.These experimental findings indicate that our approach exhibits commendable stability and high accuracy and therefore holds great significance for single-pixel imaging development and classical phase imaging innovation.
