【摘要】：非相干數(shù)字全息術(shù)是當(dāng)前國(guó)際前沿重要研究領(lǐng)域之一。傳統(tǒng)全息術(shù)由于采用相干光源照明會(huì)在全息圖記錄過程中引入大量散斑噪聲和寄生干涉,且對(duì)設(shè)備和記錄條件要求很高,極大地限制了其應(yīng)用范圍。采用非相干光源照明的非相干全息術(shù)則可完全避免這些問題。菲涅耳非相干相關(guān)全息術(shù)是非相干全息術(shù)中最重要的類型之一。本文簡(jiǎn)要說明了菲涅耳非相干全息術(shù)的原理與特點(diǎn),重點(diǎn)分析了該技術(shù)在抑制直流項(xiàng)和共軛像干擾、提高成像分辨率、改善再現(xiàn)像質(zhì)量及相關(guān)應(yīng)用等方面的研究進(jìn)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.
