Аннотация
© 2021, Pleiades Publishing, Ltd.Abstract—A method is proposed for the synthesis of self-focusing amplitude diffractive optical elements (DOEs) without a carrier spatial frequency for operation in diverging beams and forming a single focused diffraction order, which can occupy the entire region of the DOE image being reconstructed due to the absence of the need for spatial separation of orders. The synthesis takes place in two stages. The first is carried out by an iterative algorithm similar to the Gerchberg–Saxton algorithm, with the differences that the synthesized DOE is amplitude rather than phase, and the incident wavefront is diverging spherical. Next, the direct search with a random trajectory method is applied. As a result, for a binary amplitude DOE, it was possible to achieve synthesis error values of 6% and a diffraction efficiency of 6%. The results of the experimental implementation of DOE using a digital micromirror device are presented.
