数字全息和计算程式
计算全息图的制作和再现过程主要分为以下几个步骤：
1抽样。得到物体或波面在离散样点上的值。
2.计算。计算物光波在全息平面上的光场分布。
3.编码。把全息平面上光波的复振幅分布编码成全息图的透过率变化。
4.成图。在计算机控制下，将全息图的透过率变化在成图设备上成图。如果成图设备分辨率不够，再经光学缩版得到实用的全息图。
5.再现。这—步骤在本质上与光学全息图的再现没有区别。
(Digital Holography and CGH for calculating the production and reproduction process is divided into the following steps: 1 sampling. Be objects, or wavefront-like point in the discrete value. 2. Calculated. Calculation of complex light plane in the holographic optical field distribution. 3. Coding. The hologram plane the complex amplitude distribution of light into a hologram coding changes in the transmittance. 4. As Fig. Under the control of the computer, the hologram transmittance change in the mapping device mapping. Mapping equipment, if not resolution, then reduced by the optical version of a hologram to be practical. 5. Reproduction. This is- these in essence a hologram and the optical reproduction is no different.)
