【摘要】：非相干数字全息术是当前国际前沿重要研究领域之一。传统全息术由于采用相干光源照明会在全息图记录过程中引入大量散斑噪声和寄生干涉,且对设备和记录条件要求很高,极大地限制了其应用范围。采用非相干光源照明的非相干全息术则可完全避免这些问题。菲涅耳非相干相关全息术是非相干全息术中最重要的类型之一。本文简要说明了菲涅耳非相干全息术的原理与特点,重点分析了该技术在抑制直流项和共轭像干扰、提高成像分辨率、改善再现像质量及相关应用等方面的研究进展。
[Abstract]:Incoherent digital holography is one of the most important research fields in the world.Traditional holography can introduce a large amount of speckle noise and parasitic interference in the hologram recording process because of the use of coherent light source illumination, and the requirements for equipment and recording conditions are very high, which greatly limits its scope of application.Incoherent holography with incoherent illumination can completely avoid these problems.Fresnel incoherent correlation holography is one of the most important types of incoherent holography.In this paper, the principle and characteristics of Fresnel incoherent holography are briefly described, and the research progress of Fresnel incoherent holography in suppressing the interference of DC and conjugate images, improving imaging resolution, improving the quality of reconstructed images and its related applications is analyzed.
