Abstract: The design of efficient methods for calculating complex transmission function of a phase diffractive optical element (DOE) with a given multichannel intensity distribution has been performed. Based on numerical modeling, testing of the multichannel phase DOE designed for detecting wavefront aberrations, has been carried out. Numerical modeling was used to estimate the diffraction efficiency and root-mean-square error characteristics of DOEs. The possibility of using the partial coding algorithm to design the DOE matched with 25 and 49 basis functions has been shown. The smallest error of 15% is achieved with diffraction efficiency values of 52%. The maximum diffraction efficiency of 85% using the proposed algorithm can be achieved with the error value equals to 31%.

Keywords: diffractive optical element, multichannel, wave aberrations, diffraction efficiency.
