Mixed constraint in global and sequential hologram generation

In this paper, we implement a mixed constraint scheme with a global Gerchberg-Saxton algorithm for the improved generation of phase holograms from multiplane intensity distributions. We evaluate the performance of the proposed method compared to the mixed constraint sequential Gerchberg-Saxton algorithm, as well as the implementation of both schemes in several scenarios involving intensity distributions of up to nine independent planes. We also show that a careful selection of the parameters involved in the mixed constraint hologram generation technique can lead to even greater improvements in reconstruction quality. We present numerical results validating the effectiveness of our proposal. (C) 2021 Optical Society of America

Automated summary

In this paper, a mixed constraint scheme using a global Gerchberg-Saxton algorithm is implemented for the improved generation of phase holograms from multiplane intensity distributions. The performance of the proposed method is evaluated compared to other algorithms in various scenarios involving intensity distributions of up to nine independent planes. The careful selection of parameters in the mixed constraint hologram generation technique can lead to even greater improvements in reconstruction quality, as validated by numerical results.
