全息汽车尾灯设计和研究

Design and Research of Holographic Automotive Rear Light

随着汽车尾灯技术的发展,人们对汽车尾灯的个性化和立体化的图像显示功能有了更高的追求。针对这一现状,基于全息技术原理,提出透射式和反射式两种全息汽车尾灯方案,对汽车尾灯进行三维建模,并制作了汽车尾灯及其光学元件,实现了汽车尾灯的三维图像显示功能。对全息汽车尾灯的三维显示效果及其显示性能参数进行了试验测试和结果分析。其中,透射式全息汽车尾灯的衍射效率可达28.75%,平均透光率高达86.83%,有较好的三维立体显示效果。反射式全息汽车尾灯在白光下也可呈现出较为清晰的三维立体图像。

With the development of automotive rear light technology,people have a higher pursuit of the personalized and three-dimensional image display function of automotive rear lights.In response to this situation,based on the principle of holographic technology,this paper proposes two holographic car taillight schemes,transmission type and reflection type,three-dimensional modeling of automotive rear lights,and production of automotive rear lights and optical components to realize the three-dimensional image display of automotive rear lights.The three-dimensional display effect and display performance parameters of holographic automotive rear lights were tested and analyzed.Among them,the diffraction efficiency of the transmissive holographic automotive rear light can reach 28.75%,and the light average transmittance is higher than 86.83%,which has a good three-dimensional display effect.Reflective holographic car taillights can also present clearer three-dimensional images under white light.
