A holographic automotive head-up display was developed to project 2D and 3D ultra-high definition (UHD) images using LiDAR data in the driver’s field of view. The LiDAR data was collected with a 3D terrestrial laser scanner and was converted to computer-generated holograms (CGHs). The reconstructions were obtained with a HeNe laser and a UHD spatial light modulator with a panel resolution of 3840×2160 px for replay field projections. By decreasing the focal distance of the CGHs, the zero-order spot was diffused into the holographic replay field image. 3D holograms were observed floating as a ghost image at a variable focal distance with a digital Fresnel lens into the CGH and a concave lens.

Driver's access to information about navigation and vehicle data through in‐car displays and personal devices distract the driver from safe vehicle management. The discrepancy between road safety and infotainment must be addressed to develop safely operated modern vehicles. Head‐up displays (HUDs) aim to introduce a seamless uptake of visual information for the driver while securely operating a vehicle. HUDs projected on the windshield provide the driver with visual navigation and vehicle data within the comfort of the driver's personal eye box through a customizable extended display space. Windshield HUDs do not require the driver to shift the gaze away from the road to attain road information. This article presents a review of technological advances and future perspectives in holographic HUDs by analyzing the optoelectronics devices and the user experience of the driver. The review elucidates holographic displays and full augmented reality in 3D with depth perception when projecting the visual information on the road within the driver's gaze. Design factors, functionality, and the integration of personalized machine learning technologies into holographic HUDs are discussed. Application examples of the display technologies regarding road safety and security are presented. An outlook is provided to reflect on display trends and autonomous driving.

Modern touch control infotainment systems in vehicles present distractions to drivers and endanger road safety. Current industrial head-up displays (HUDs) require the driver to shift the gaze from the road towards a region on the 2D windscreen. Panoramic augmented reality holographic color projections in could prevent driver distraction. This is an inclusive tool to incorporate all members of society into the transportation sector. A 4k color augmented reality holographic automotive head-up display was developed to project road obstacles in 360° in the driver's field of view. This technology could be useful for drivers, including elderly and disabled populations.

Pixel by pixel brightness control was achieved in the 3D 4k holographic replay field results. High accuracy and brightness control is required for maps in military applications and real-time head-up displays.
