We present a design approach for diffractive phase elements (DPE’s) that generate point/ring patterns in optical systems illuminated by monochromatic and dual-wavelength light based on the general theory of phase retrieval. We carry out the numerical simulations for several diffractive patterns and appraise the performance of the designed DPE’s. The results show that the designed DPE’s can generate the desired point/ring patterns with a large signal-to-noise ratio, high average diffraction efficiency, and low color cross talk.
