计算全息双通道半色调编码技术的研究

本文在罗曼型编码的基础上,运用空间脉冲调制技术,提出了新型的编码技术——双通道半色调编码。双通道半色调型编码用两个圆形通光孔代替矩形孔,以两个圆孔面积及位置来记录两个物体的全息信息,加快了计算速度。记录的两个平面物体同时再现在同一衍射级的相同或不同方向上,在空间完全分离开来,从而实现了载波信息的通道变化。文中给出了相应的原理和实验结果。

Study of Two-Channel and Half-Tone Coding Technology of Computer-Generated Hologram

In this paper,based on the coding of Lohmann,a new type coding the two-channel and half-tone code are put forward by using the space pulse modulation technique.The two-channel and half-tone code uses structure parameter of two circular-holes in-stead of rectangle hole and records the hologram information by area and position of circular-hole,this can enhance the speed of com-putation.And the two plane objects were reconstructed in the same or different direction and same diffraction order simultaneously,and...
