The dynamic Coarse Integral Holography (CIH) display demonstrated previously can scan the low space bandwidth product (SBP) holographic images delivered by a high bandwidth spatial light modulator (SLM) to form a hologram array for angular tiling of the 3D images for a large field-of-view but only a modest size despite the utilization of the full bandwidth of the SLM in use. In this paper, we propose a scalable approach using seamless spatial tiling of the full bandwidth images generated by two high bandwidth SLMs using a resonant scanner and a high performance galvanometric scanner for a scalable CIH display capable of achieving twice of the final image size and doubled horizontal field-of-view (FOV). A proof-of-concept system is demonstrated with integrated full-parallax holographic 3D images. The proposed method has the potential to tile images generated by more than two SLMs for scalable large size and wide FOV holographic displays.

具有集成空间图像平铺的可缩放粗体整体全息视频显示

先前演示的动态粗略整体全息（CIH）显示器可以扫描由高带宽空间光调制器（SLM）传送的低空间带宽积（SBP）全息图像，以形成用于大范围3D图像的角度平铺的全息图阵列，尽管使用了正在使用的SLM的全部带宽，但只有适中的大小。在本文中，我们提出了一种可扩展的方法，该方法使用由两个高带宽SLM使用谐振扫描仪和高性能振镜扫描仪生成的全带宽图像的无缝空间平铺来实现可扩展的CIH显示器，从而实现最终图像尺寸的两倍和两倍水平视场（FOV）。通过集成的全视差全息3D图像演示了概念验证系统。
