本文提出了一种三基色计算机全息设计波长的优化方法。通过合成三幅计算全息图再现的三原色图像，简单地实现了高清晰度计算全息图（CGH）的全色再现。然而，在重建中会出现色差，因为非相干光源，如LED通常用于照明。由于这些色差的变化依赖于CGH的设计波长以及照明光谱的形状，基于CGH的模拟重建的优化技术，以获得最不显眼的色差从特定的光源光谱。
We propose a technique for optimization of design-wavelengths in trichromatic computer holography. Full color reconstruction of high-definition computer-generated holograms (CGH) is simply realized by combining three primary color images reconstructed by three CGHs. However, chromatic aberrations occur in the reconstruction, because incoherent light sources such as LED are commonly used for the illumination. Since these chromatic aberrations change dependently on the design-wavelengths of CGHs as well as the shape of illumination spectra, optimization techniques based on simulated reconstruction of CGHs is presented to obtain the most unobtrusive color aberration from spectra specific to the light source.
