摘要
The relationship between the transmission distance and the number of Fresnel zone plate rings is evaluated. The influence of different transmission distance and the number of Fresnel zone-plate rings are analyzed. Their parameters of the best reconstructed image are obtained. A point light source is taken as an example, a phase-only spatial light modulator with the resolution of 3840 x 2160 pixels and the pixel interval of 3.74 mu m is used for experimental verification. The numerical simulation and optical experiment results show that the optimal reconstructed image has a transmission distance of 200 mm. Meanwhile, the optimal Fresnel zone ring number is 8 under the same conditions. This study provides the optimal parameters for the spatial light modulators with different size.
