摘　　要：基于制作全息灯箱背光源的需要,从色度上分析研究了发光二极管用于彩色全息图照明的可行性,对使用发光二极管和定向照明卤钨灯照明再现的彩色全息图进行了色度测量与评价.实验测量并计算了发光二极管与卤钨灯光谱功率分布RGB成分比,给出了在CIE1976均匀颜色空间中两种光源再现图像与原图像之间的色差.结果表明,发光二极管用作彩色全息图照明光源是可行的,可以作为全息灯箱背光源.Based on making holographic lampbox backlights need,the possibility of using LEDs as the illumination sources for reconstruction of color holograms is studied on chrominance,compared with tungsten halogen spotlights which are common practiced currently.And the reproduced images those are displayed by a LED and a tungsten halogen spotlight are evaluated.In experiments,the RGB proportions in spectral power distributions of a LED and a tungsten halogen spotlight are calculated.Color differences,in CIE1976 uniform color space,between an original picture and the reproduced images are also calculated and analyzed separately.Results indicate that it is feasible to use LEDs to illuminate color holograms,and feasible to use LEDs as holographic lampbox backlights.
