物理可实现的相位编码压缩成像
Physical Realizable Phase Encoding Compressed Imaging
摘要
Abstract
Compressed Imaging (CI) is one of the most important research area of compressed sensing.Analyzing the constraints on actual measurement matrix and measurement values in CI,a frequency domain phase encoding CI method is proposed,which can be physically realized based on 4-f optical architecture.This method exploits two-way optical architecture compensated for the phase-encoding CI to implement the value non-negative for recording,and then accurately recover the original image from the measured values,to resolve inconsistencies between the theoretical requirements and physical constraints in CI.With measured values can be obtained in a single exposure,such method can reconstruct the original image precisely without additional information,and is a very practical scheme for physical realization of CI.Simulation experiments demonstrate that our proposed method can effectively capture compressed measurements of image and achieve super-resolution reconstruction.关键词
