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。Incoherent digital holography is one of the important research fields of the current international frontier.Due to the use of coherent light source a lot of speckle noise and spurious interference will be introduced in traditional holography.And it requires high equipment and strict recording conditions,which will seriously limit its application range.Incoherent holography with incoherent light source can completely avoid these problems.FINCH is one of the most important types of incoherent holography.In this paper,the principle and characteristic of FINCH is briefly introduced.Suppression of DC term and conjugate image,improvement of imaging resolution and the reconstructed image quality and the applications of FINCH are analyzed in detail.
