Paper Abstract

In the optoelectronic reconstruction of full-color hologram, transverse and longitudinal chromatisms are introduced due to the hologram is sensitive to wavelength, which makes the colorful image fuzzy. The image quality is also affected by the characteristic of the spatial light modulator used in optoelectronic projection system. Multi-order diffraction images occurred due to the ratio of active area and dead area (fill rate). In the colorful holographic projection system, three lasers with red, green, and blue color are applied as the light sources, color crosstalk due to the switching of the different lasers also impairs the image quality. In order to improving the image quality of full color holographic projection system, this paper analyzes the effect of the fill rate and the color crosstalk on the reconstruction image quality. Transverse and longitudinal chromatisms are removed by resampling the object information and loading a specially designed virtual phase distribution in the computer hologram respectively. We proposed time sequence updating chart of RGB laser to solve the problem of color crosstalk. Experimental results are also provided to verify the improvement of the image quality.
