ホログラフィック光指向性制御によるフルパララックス透明3Dディスプレイの開発

抄録

In recent years, industrial application development of MR (Mixed Reality) technology using smart glasses has been actively carried out. However, in order to share information with multiple people, it is necessary to prepare smart glasses for each person, which poses a problem in terms of introduction cost. If a transparent, large-area 3D display is realized at low cost, MR display will be possible by superimposing a stereoscopic image on a real object. Therefore, we are developing brand-new method for MR display of full-parallax 3D images by controlling the directivity of light with a transparent holographic screen. In this paper, we describe the basic principle and the method of generating a projected image format that combines parallax image groups. In addition, we report the results of the exposure trial of the holographic screen and the results of the principle demonstration experiment of 3D image display.
