Lenslet array near-eye displays (LA-NEDs) generate virtual images that appear within the observer’s field of view (FOV). While this innovation is pivotal in creating lightweight NEDs, the intricacies of parameter performance during the design process introduce complexities to system development. Additionally, LA-NEDs, a type of pupil-forming technology, entail intricate imaging optical paths, which amplify design challenges and incur high costs for custom-made aspherical lens arrays (ALA). This paper addresses these challenges through a comprehensive exploration of ALA-NEDs. Focusing on simulation-based insights and performance evaluations, it aims to deepen understanding of their applications and capabilities. Through simulation, nuanced performance characteristics are uncovered, providing a foundational knowledge base for informed decision-making in integrating these arrays into immersive visual systems. The study further investigates the impact of various parameters on the imaging quality of ALA-NEDs. Assigning appropriate weights to these parameters, quantifies their influence, enabling optimization and customization of systems for enhanced visual experiences. Additionally, practical guidance for ALA-NEDs design is offered by identifying key parameters crucial to imaging quality, serving as a roadmap for future developments and fostering advancements in NEDs. This research significantly contributes to the field by guiding system design. The insights gained pave the way fo...
