The resolution redistribution (RR) technique can increase the horizontal viewing-zone angle and screen size of electronic holographic display. The present study developed a zone plate method that would reduce hologram calculation time for the RR technique. This method enables calculation of an image displayed on a spatial light modulator by performing additions of the zone plates, while the previous calculation method required performing the Fourier transform twice. The derivation and modeling of the zone plate are shown. In addition, the look-up table approach was introduced for further reduction in computation time. Experimental verification using a holographic display module based on the RR technique is presented.
分辨率重新分配（RR）技术可以增加电子全息显示器的水平视区角度和屏幕尺寸。本研究开发了一种波带片方法，该方法可减少RR技术的全息图计算时间。这种方法通过对波带片进行相加运算来计算显示在空间光调制器上的图像，而之前的计算方法需要进行两次傅里叶变换。文中展示了波带片的推导和建模。此外，还引入了查找表方法以进一步减少计算时间。本文还介绍了使用基于RR技术的全息显示模块进行的实验验证。
