矢量全息技术的研究进展与应用

Research progress and applications of vectorial holography

全息技术能够记录和重建物光波的全部信息,自问世发展至今已经取得了显著的进步。近年来,矢量全息的出现为这一领域带来新的发展。矢量全息技术不仅继承了传统标量全息技术记录振幅和相位的能力,还额外引入了对偏振维度的调控,因此能够显著提高记录信息的密度,并在多个领域得以广泛应用。本文旨在从偏振调控的角度深入探讨矢量全息技术。首先介绍了标量全息技术和矢量全息技术的概念,并比较了二者的优缺点,重点阐述了矢量全息技术的优势;然后详细地介绍了矢量全息技术的两种偏振态调控方式,包括对入射光和出射光偏振态的调控;同时阐述了矢量全息技术在三维显示和加密领域的应用;最后总结了矢量全息技术目前面临的挑战,并展望了其未来的发展趋势。

Holography,which can record and reconstruct all the information of object light waves,has made remarkable progress since its invention.In recent years,the emergence of vectorial holography has brought new developments to this field.Vectorial holography not only inherits the ability to record the amplitude and phase of traditional scalar holography but also introduces the additional control of the polarization dimension,which can significantly improve the density of the recorded information and has been widely used in many fields.This paper discusses vectorial holography in depth from the perspective of polarization modulation.Firstly,the concepts of scalar holography and vectorial holography are introduced,and their advantages and disadvantages are compared.Then,the two polarization modulation methods of vectorial holography are introduced in detail,including the polarization modulation of incident light and output light.Meanwhile,the applications of vectorial holography in the field of 3D display and encryption are described.Finally,the challenges faced by vectorial holography are summarized,and the future development of vectorial holography is expected.
