我们提出了一种使用全息光学元件（HOE）的立体头戴式显示器（HMD）。该显示器使用HOE作为全息组合器，而不是传统HMD使用的半反射镜。单个HOE可以通过其自身的特性记录多个光学图像，即角度选择性和波长选择性：因此，我们认为，作为组合器的HOE具有将立体图像分离到左右眼的特点，它既具有对外界的透明性，又具有对小型LCD或CRT等电子显示器显示的虚像的反射率，证明了采用李普曼全息图的头盔显示器具有小型化、轻量化、大视场等优点。此外，我们还利用我们的新头戴式显示器开发了混合现实系统。这种头盔显示器可以适用于虚拟现实领域，特别是混合现实，我们必须同时观察真实的外部世界和虚拟世界。
Synopsis We propose the stereoscopic Head Mounted Display(HMD) using Holographic Optical Elements(HOE). This display uses HOE as the holographic combiner instead of half mirror that is used by conventional HMD. A single HOE can record the multiple optical images by the characteristic in itself, that is angular selectivity a~d wavelength selectivity: Therefore, the HOE as the combiner has the feature which can separate the stereoscopic images onto the left and right eyes and it has high efficiency both transparency for outside world and reflectance of virtual images shown by electrical display like as small LCD or CRT and so on. In this paper we proved that the HMD using Lippmann hologram has the potentiality of miniaturization, lightening, wide field of vision for outside world. In addition, we have developed the Mixed Reality system by using oUr new HMD. This HMD can be suitable to the Virtual Reality field, especially Mixed Reality we have to observe both the real outside world and the virtual world at the same time.
