X-SectionScope: cross-section projection in light field clone image

Abstract

In this paper, we propose a novel interactive 3D information visualizing display that superimposes a cross-sectional image in an aerial volumetric image of an object. Figure 2 shows a system configuration. A user can see internal images of the object, such like an X-ray image, by inserting a semi-transparent handheld screen in a cloned floating image. We use two Micro Mirror Array Plates (MMAPs) to reproduce a Light Field Clone (LFC) image. The MMAP (Aerial Imaging Plate, ASUKANET. Co., Ltd.) was designed for reconstructing aerial images in midair based on double reflections. The LFC image is a reconstructed floating 3D image which can be seen without wearing any glasses. In the HaptoClone system [Makino et al. 2015], they proposed the use of two MMAPs to reproduce LFC image of the object. By contrast, we use additional two general mirrors in the proposed system. With this configuration, the realistic LFC image appears next to the object keeping the facing direction same. Users can see both the real object and its cloned image at the same time.
