With the development of the micro/nanolithography, the optic–optic or optic–electronic modulation devices with different pixel shapes and sizes can be used for three-dimensional(3D) dynamical holographic display. The influence of different parameters of the modulation devices on the image quality of the 3D reconstructed object is analyzed for two cases: the phase-only computer-generated holography(CGH) and the complex amplitude CGH. The results quantitatively show that the pixel shape of the modulation devices will affect the quality of the holographic image.
