Color reproduction of multi-wavelength digital holography using a color correction algorithm

This work describes color reproduction of multi-wavelength digital holographic recording and reconstruction of real objects based on color correction procedures. Color correction primarily consists of tone correction and chromaticity correction for reconstructed images from a multiwavelength digital hologram. With recording and reconstruction knowledge from a standard ColorChecker chart, a color profile can be generated to characterize the color properties of the multi-wavelength digital holography system and then use this profile for color reproduction of different target images. The color accuracy of reconstructed images via the proposed method is demonstrated experimentally.
