摘要
柱状透镜阵列可以用来扭曲光线使“物体消失”,即通过柱状透镜阵列观察物体时可实现隐形效果.根据光在空间和介质中的传播特性,结合几何光学和光度学理论,提出了临界隐形物距的概念,可用来衡量柱状透镜阵列的隐形效果.通过光学物理场仿真和实验,探究了柱状透镜阵列属性包括透镜单元间距、曲率半径、折射率以及物体几何形状等因素对该隐形现象的影响.理论与实验相辅相成,有助于学生理解柱状透镜阵列导致物体隐形的产生机制,也可作为大学物理实验教学中的创新设计性实验案例.
The lenticular lens array can be used to distort the ray to make object disappear,that is,the invisible effect can be realized by the lenticular lens.According to the propagation characteristics of light in space and medium,combined with the theory of geometric optics and photometry,the concept of critical invisible object distance was proposed,which could be used to measure the invisibility of lenticular lens.Through the optic simulation and experiments,the influence of lenticular lens on the invisibility was investigated,including lenticular lens unit distance,radius of curvature,refractive index and object geometry.The theory and experiment complemented each other in this study,which was helpful for students to understand the invisibility mechanism observed by lenticular lenses,and could be used as an innovative and designing project for college physics experiment teaching.
