N2 - Complex amplitude holography contains all the information of the holographic plane including amplitude and phase, to achieve high-precision image reconstruction in the original three-dimensional (3D) space. A new physical means for the realization of holograms is provided by the complex amplitude metasurfaces with an ultra-thin and ultra-flat electromagnetic wave regulation element. However, the complexity of the design is also greatly improved because of the simultaneous adjustment of amplitude and phase. In this paper, we analyze and compare the effect caused by the range of normalized transmission amplitude reduction on the imaging quality. The numerical simulation results show that appropriately reducing the range of normalized transmission amplitude can not only simplify the design complexity, but also make the amplitude-phase response closer to the preset value, thus improving the imaging quality and the efficiency.
