A miniaturized augmented reality head‐up display system based on real‐time holographic with dynamic depth variation

Abstract Augmented reality head‐up display (AR‐HUD) systems utilizing computer‐generated hologram technology have emerged as a focal point of optical innovation. Traditional display systems often rely on arrays of projectors or multiple spatial light modulators (SLMs) for multidepth projection; thus, these systems are typically complex and expensive. To address these challenges, the present study developed a miniaturized AR‐HUD system that integrates an advanced driver assistance system (ADAS) with holographic display technology. By leveraging a single SLM for spatial multiplexing, this AR‐HUD system achieves a streamlined design, enhancing real‐time data visualization and situational awareness. The proposed AR‐HUD system has a simple architecture and relatively low costs, and it advances driving safety and convenience by dynamically adjusting the depth of holographic images through deep learning techniques.
