本文提出了一种设计多波长成像金刚石旋转全息图的新方法。该方法允许DTH的设计，重建不同的独立的强度分布时，在远场用不同的波长照射。它是基于一种新的方法，允许利用非线性共轭梯度（NCG）方法的多波长图像形成的第一次，我们的知识。这种新的方法已被改编为将内在的，制造相关的DTH的属性。我们目前的实验结果表明，图像形成具有高品质，没有显示图案之间的串扰。
In this paper, we present a new method for the design of diamond turned holograms (DTHs) for image formation with multiple wavelenghts. The approach allows the design of DTHs that reconstruct different independent intensity distributions in the far field when illuminated with different wavelengths. It is based on a new approach that allows the utilization of the nonlinear conjugate gradient (NCG) method for multiple wavelength image formation for the first time to our knowledge. This new approach has been adapted to incorporate the intrinsic, fabrication related properties of DTHs. We present experimental results demonstrating image formation with high quality and without crosstalk between the displayed patterns.
