| Outline of Final Research Achievements |
This research proposes a new 3D display method to enable visual, thermal, and acoustic floating display. There are differences in electromagnetic waves and acoustic waves, such as wavelength, transverse wave, and longitudinal wave. However, imaging methods based on reflection are applicable for waves that maintain incident angle equals to reflected angle. We have developed a special crossed-mirror array (CMA) for visual, thermal, and acoustic floating display. The special CMA is composed of two CMAs: one CMA for visible light and far-infrared radiations has 4 mm x 4 mm apertures; the other CMA has 15 cm x 15 cm apertures to converge acoustic waves. The CMA for acoustic waves is made of transparent acrylic plate and does not influence converging lights. We have confirmed visual, thermal, and acoustic floating image and found that local heating assists reaching of a viewer’s hand to the floating position.
