摘要
虚拟现实(VR)/增强现实(AR)是新兴的人-机交互显示技术,其光学元件的集成化、轻量化与定制化是先进VR/AR技术的必然要求,全息高分子材料是关键.本文介绍了VR/AR近眼显示系统及重要参数,回顾了全息高分子材料在VR/AR显示中的重要应用,讨论了全息高分子材料的性能与VR/AR显示效果的关系,重点介绍了全息高分子材料的折射率调制度、光散射损失和体积收缩率的调控策略,最后指出了现有全息高分子材料在先进VR/AR应用中的不足,并展望了未来发展方向.
As emerging high-tech and intelligent display technologies allowing for real-time human-computer interactions,virtual reality(VR)and augmented reality(AR)can provide completely immersive virtual scenes to users or offer users the perfectly merged scenes of real world with virtual objects.Their unique capabilities are primarily ascribed to the predesigned optical elements in the VR/AR setups.Since multifunction integration,weight reduction and customization of VR/AR setups are in urgent needs for developing advanced VR/AR technologies,it is critical to develop novel optical elements using advanced materials.To this end,holographic polymer materials can play a central role.In this feature article,the VR/AR near eye display systems and key parameters are firstly overviewed,followed by the discussion of the application of holographic polymer materials in VR/AR display.Subsequently,the relationship of VR/AR performances to the properties of holographic polymer materials is discussed,and strategies to improve the refractive index modulation,decrease the scattering loss and volume shrinkage of holographic polymer materials are highlighted.Finally,the shortage and future directions of current holographic polymer materials are pointed out,respectively,for advancing the VR/AR technologies.
