提出了一种使多个物体的再现像间有相互遮掩效果的彩虹全息记录方法。在主全息图记录光路中设置系列互补的挡光屏,对不同的物体分别进行记录;所得到的彩虹全息图再现时,左右移动观察,将看到不同物体的再现像在视场中逐渐交替出现,沿挡光屏边缘相互遮掩。给出了挡光屏的设置参数,并完成了“天狗袭日”彩虹全息图的设计和制作,获得了满意的效果。
A rainbow holographic recording method is proposed to make the reconstructed images of multiple objects mutually obscure each other. In the hologram recording light path, a series of complementary light-blocking screens are set up to record different objects separately. When the obtained rainbow hologram is reproduced, the observer moves left and right to observe that the reproduced images of different objects gradually alternate in the field of view Appear, along the edge of the screen to hide each other. The setting parameters of the screen are given, and the design and manufacture of the Rainbow Hologram of “Tenguang Striking on the Sun” are completed, and satisfactory results are obtained.
