Abstract
A color matching method for improving the color reproduction quality
of color computer-generated holography (CCGH) is proposed. It is found that
the amplitude of object wave in CCGH is related with object's color quantity
in computer display colorimetric system, three primary wavelengths of CCGH
and spectral distribution of illuminant source. Thus, this paper presents
the conversion relationship between color quantity in computer display colorimetric
system and amplitude of object wave in CCGH, which can improve the color quality
of holographic image. In order to demonstrate the effectiveness of the proposed
method, two experiments are conducted. The CCGH targets are respectively two-dimensional
(2D) color object, three-dimensional (3D) gray and color mixed object. The
experimental results demonstrate that the proposed color matching method of
CCGH is effective. It has practical applications in both static and real-time
dynamic holographic display, especially in high quality CCGH display.
