Wavefront-based holographic lens optical power model for augmented reality applications

The use of holographic optical elements (HOEs) has grown significantly in recent years, particularly in augmented reality (AR) and see-through display systems. Among them, holographic lenses (HLs) have attracted special interest due to their versatility, light weight, and adaptability to compact optical architectures. In this work, we present a theoretical model that describes the optical power of HLs as a function of the recording geometry, relating it to the angles and distances involved in the holographic process. The influence of these parameters was computationally modeled, and the results were validated experimentally using HLs recorded in 100 μ m layers of the green sensitive photopolymer Biophotopol. The strong agreement between theoretical and experimental results confirms the model’s accuracy and its applicability to the design and optimization of holographic components for AR systems.
