Colorimetrical Research on LED Displaying Color Holograms
LED用于彩色全息图照明的色度研究

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.
