We propose a new method for implementing 3D/2D convertible feature in the projection-type integral imaging by using concave half mirror array. The concave half mirror array has the partially reflective characteristic to the incident light. And the reflected term is modulated by the concave mirror array structure, while the transmitted term is unaffected. With such unique characteristic, 3D/2D conversion or even the simultaneous display of 3D and 2D images is also possible. The prototype was fabricated by the aluminum coating and the polydimethylsiloxane molding process. We could experimentally verify the 3D/2D conversion and the display of 3D image on 2D background with the fabricated prototype.
我们提出了一种通过使用凹面半反射镜阵列在投影型积分成像中实现3D/2D可转换特征的新方法。凹面半反射镜阵列对入射光具有部分反射特性。反射项由凹面镜阵列结构调制，而透射项不受影响。凭借这种独特的特性，3D/2D转换甚至3D和2D图像的同时显示也是可能的。该原型是通过铝涂层和聚二甲基硅氧烷成型工艺制造的。我们可以通过制造的原型实验验证3D/2D转换以及在2D背景上显示3D图像。
