Holography was originally invented for the purpose of magnifying electron microscopic images without spherical aberration and has been applied to photography for recording and reconstructing three-dimensional objects. Although it has been attracting scientists and ordinary people in the world, it is still a technology in science fiction movies. In this review, we discuss a new version of holography that uses surface plasmons on thin metal film. We discuss conventional holography and its drawbacks, such as overlapping of ghost and background due to the contribution of unnecessary diffraction and monochromacy for avoiding the unwanted diffraction components of different colors. Surface-plasmon holography is a version of near-field holography to overcome drawbacks of conventional holography. Comparison with conventional and volume holography for color reconstruction is discussed in reciprocal lattice space. Localized mode of surface plasmons and meta-surface holography are also reviewed, and feature perspectives and issues are discussed.
全息术最初是为了放大无球差的电子显微镜图像而发明的，并已应用于摄影领域，用于记录和重建三维物体。尽管它一直吸引着世界各地的科学家和普通人，但它仍然是科幻电影中的一项技术。在这篇综述中，我们讨论了一种使用薄金属膜表面等离子体激元的新型全息术。我们讨论了传统全息术及其缺点，例如由于不必要的衍射贡献导致的重影和背景重叠，以及为避免不同颜色的不需要的衍射成分而采用的单色性。表面等离子体激元全息术是一种近场全息术，旨在克服传统全息术的缺点。在倒易晶格空间中讨论了与传统全息术和体全息术在颜色重建方面的比较。还综述了表面等离子体激元的局域模式和超表面全息术，并讨论了其特点、前景和问题。
