摘　　要：利用计算机制作全息图简洁和灵活性,在光学周视彩虹全息的基础上提出了计算周视平板彩虹全息。在菲涅耳衍射理论的近似框架下,从理论推导出基元周视全息的物光分布。实际物体在记录面上的物光分布可以看成是物体上所有物点的基元周视全息物光分布的叠加。根据这一原理,模拟光学全息原理,计算出物体周视全息的物光和参考光的干涉条纹,从而获得平板周视全息图。该方法克服了光学平板周视全息在制作光路上的复杂性,使得周视全息图的制作简便易行。给出了实验证明。The computer-generated circular-viewing plane rainbow hologram was proposed, based on the optical circular-viewing plane rainbow hologram. With the approximation in Fresnel diffraction theory, the distribution of the object wave in the elementary circular-viewing hologram is deduced on theory. To an object, the distribution of the object wave on the recording plane is the sum of all the distributions of the elementary circular-viewing hologram. With this idea, the distribution of the fringes resulted from the interference between the object wave and the reference wave was computed. According to the theory of optical circular-viewing hologram, the circular-viewing plane hologram was gotten. Overcoming the complexity of the optical designs, this approach facilitates the achievement of the circular-viewing rainbow hologram. The experimental result is also shown in this paper.
