Innovating education: MLA-based AR/VR display for learning purpose

초록

Augmented Reality (AR) and Virtual Reality (VR) display for STEM education integrate advanced optical technology with immersive learning experiences. Optical Ray Tracing software serves as the primary platform for designing these educational tools. These softwares help to assess system performance and correct optical distortions, enabling the creation of diverse STEM educational modules. Microlens Array (MLA) based AR/VR displays provide immersive, hands-on learning opportunities and foster deeper understanding. The precise selection of MLA parameters influences critical aspects such as image clarity and field of view. In this study, we have designed an MLA in Zemax Opticstudio for the sake of using in AR/VR displays. We have studied the physical properties like 2D and 3D layouts and surface profile of MLA. We have also analyzed the optical properties, including ray propagation, spot diagram, and illumination. Furthermore, a comparative analysis of the optical performance of 7 × 7 and 11 × 11 MLA arrays in a 5 × 5 mmmm2 area is also incorporated. © 2024 SPIE.
