摘要

地形测量是数字全息显微定量相位成像的关键应用。本文建立了反射式数字全息显微镜，重建了具有阶跃特征的样品的相位图像，并提出了一种基于迭代自适应双边滤波器的噪声抑制方法来降低相位相干噪声。提出的去噪方法考虑了邻域的相位差，可以更好地识别和保持阶跃特征。实验结果证明了该方法的有效性。

Phase noise suppression based on iterative adaptive bilateral filter in digital holographic microscopy for topography measurement

Topography measurement is a pivotal application in quantitative phase imaging using digital holographic microscopy. In this paper, a reflection-type digital holographic microscope is set up to reconstruct the phase image of the sample with step characteristics, and a noise suppression approach based on an iterative adaptive bilateral filter is proposed to reduce phase coherent noise. The proposed denoising approach considers the phase difference in the neighbourhood to better identify and preserve step characteristics. Experimental results demonstrated the effectiveness of the proposed method.

期刊介绍： The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope. Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. General topics covered include: • Optical and photonic materials (inc. metamaterials) • Plasmonics and nanophotonics • Quantum optics (inc. quantum information) • Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers) • Coherence, propagation, polarization and manipulation (classical optics) • Scattering and holography (diffractive optics) • Optical fibres and optical communications (inc. integrated optics, amplifiers) • Vision science and applications • Medical and biomedical optics • Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy) • Imaging and Image processing
