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.
开发了一种全息汽车抬头显示器，用于在驾驶员视野中使用激光雷达数据投射二维和三维超高清（UHD）图像。激光雷达数据通过三维地面激光扫描仪收集，并转换为计算机生成的全息图（CGH）。使用氦氖激光器和面板分辨率为3840×2160像素的超高清空间光调制器进行重放场投影，从而获得重建图像。通过减小CGH的焦距，零级光斑扩散到全息重放场图像中。通过数字菲涅耳透镜和凹透镜，在可变焦距下观察到三维全息图作为重影图像漂浮着。
