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

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.
