Embodiment Construction
[0031] Preferred embodiments of the present invention are described in detail as follows in conjunction with accompanying drawings:
[0032] This true color 3D object holographic display method, as attachedfigure 1 As shown, the specific operation steps are: ① Decompose the chromatic image information of the true-color three-dimensional object into three color components of red, green and blue (RGB) according to the principle of colorimetry, and the information of each color component contains the corresponding amplitude information and depth information; ②Calculate the kinoform of each color component through Fresnel scalar diffraction theory and random phase kinoform calculation method; ③Sequence images composed of RGB component kinoforms are simultaneously output through synchronous control to three phase-type spatial light modulators, and supplemented by laser illumination of corresponding colors; ④The receiving screen receives the reproduced images of RGB components from t...
