摘 要:为了提高全息图的彩色效果和增加其视角,结合光学全息和计算全息的优点,利用镜像法提出了一种提高全息图彩色效果和增大视角的新方法。制作方法分两步来实现,第一步,镜像迭加的分色计算全息图H1r,H1g,H1b的制作。第二步,利用光学的方法制作彩虹全息图H2。设计光路使再现的光波经平面镜反射,按光的可逆原理展开,形成大视角再现。经理论分析和实验验证,实验获得的全息图可以在大视角(约14°)情况下观察到彩色再现像,彩色效果和立体效果均较为明显。
In order to improve the color effect and the visual angle of hologram, based on the method of mirror ima- ges, a new technique is proposed to obtain a real color hologram with a large viewing angle by the combination of comput- er-generated hologram and optical hologram. There are two steps to realize the method: Firstly, computer-generated hol- ogram H1r, H1g, H1b is yielded with three image objects. Secondly, a rainbow hologram H2 is generated by optical ways. In terms of the reversibility of light path principle, an image with a wide viewing angle is reconstructed by reversing the reconstructed wave. The technique achieves a color reconstruction image with a wide viewing angle of 14°. The color effect and the stereoscopic effect of the reconstruction image is increased.
