Head up displays (HUDs) in cars are becoming increasingly common & have been shown tosignificantly reduce accident rates by keeping the drivers eyes on the roads. Conventionalautomotive HUD projection systems are limited in brightness, contrast, resolution/definition,power usage, size & colour variation. The next generation requirements for AugmentedReality & high performance HUDs initially for the luxury car market are very demanding &holographic HUDs provide a variety of advantages in each of these areas. Two TreesPhotonics have demonstrated very high quality HUDs using its highly innovative & patentedphase only holography, which are in the process of being exploited commercially. However,phase only holographic HUD requires extensive computational resource & resolution is at thelimit of current FPGA & memory technology. Additionally, the frame-rate afforded by theexisting phase only spatial light modulators is limited by the elastic properties of liquidcrystals. To provide a step change in HUD capability the project seeks to develop aholographic HUD that utilises fully complex light modulation (i.e. both amplitude & phase)driven using real-time hologram computation in order to realise the higher performancecharacteristics needed to enable key innovations in automotive HUD. The reducedcomputational complexity of this approach will allow the resolution & frame-rate of thedisplay to be enhanced far beyond the current baseline technology. Two Trees Photonics hassignificant world leading technical capability with holographic display & optical systems. Theproject will determine the most feasible modulator implementation by simulation & realise thespatial light modulator. Holographic algorithms will be developed to match the fully complexlight modulation & a demonstrator unit will be fabricated. The project is initially focused onautomotive but provides opportunities in aerospace, medical, rail, marine, near eye devices &augmented reality.

汽车中的头部显示器（HUD）变得越来越普遍，并且通过使驾驶员的眼睛注视着道路，可以显着降低事故发生率。传统的载体HUD投影系统受到亮度，对比度，分辨率/定义，功率使用，大小和颜色变化的限制。最初，豪华汽车市场的增强性和高性能HUD的下一代要求非常苛刻，全息HUD在每个领域都提供了各种优势。两种树晶型药物使用其高度创新和专利的全息图展示了非常高质量的HUD，这些全息图在商业上被剥削。但是，只有阶段全息HUD需要广泛的计算资源和解决方案，即当前FPGA和内存技术。此外，仅由空间光调节器提供的帧速率受到液体晶体的弹性特性的限制。为了提供HUD能力的步骤变化，该项目试图开发Aholographic HUD，该HUD利用了使用实时全息图计算驱动的完全复杂的光调制（即振幅和相位），以实现为启用加人类HUD中关键创新所需的较高性能术。这种方法的降低计算复杂性将使THEDISPLAY的分辨率和帧速率远远超出了当前基线技术。两棵树光子学哈斯特型世界领先的技术能力，具有全息显示和光学系统。该项目将通过仿真确定最可行的调制器实现，并实现200次灯光调制器。将开发全息算法以匹配完全复杂的调制，并且将制造演示器单元。该项目最初是集中精力的，但在航空航天，医疗，铁路，海洋，靠近眼睛设备和增强现实中提供了机会。
