How to Generate Floating 3D Images on a Flat Tabletop Surface

1 Introduction The Superconducting Submillimeter Wave Limb Emission Sounder (SMILES) was launched in September 2009 and has been installed on the exposed section of the Japanese Experimental Module (JEM, shown in Figure 1). Minor atmospheric composition in the atmosphere plays a key role in such specific changes of the global atmospheric environment as ozone layer destruction, global warming, and atmospheric pollution. The substances which have been considered to be capable of performing key roles, and just a few data of them exists because of their extremely minute concentration in the atmosphere, such as bromine monoxide (BrO) and hydroperoxy radical (HO₂) in the order of trillionth and likewise the hypochlorous acid (HOCl) at the atmospheric concentration of 10 billionth, have been detected by the SMILES. We are carrying on detailed studies on the behavior of these extremely minute amounts of molecules in the atmosphere. Objectives of the SMILES mission include the following: 1) Technological demonstration of the high-sensitivity superconducting submillimeter wave receiver system cooled with a 4K (-269℃) mechanical cooler 2) Clarification of new aspects of the global atmosphere through the super-high sensitivity observation In the joint development mission of NICT and the Japan Aerospace Exploration Agency (JAXA), NICT started the development activities for the SMILES in 1997. SMILES observed the atmospheric emission in the submillimeter-wave region with heterodyne detection using SIS mixer and HEMT amplifier. While the design lifetime of instruments was one year, the local oscillator failed in April 2010, and since June 2010, the mechanical cooler has failed to reach 4K, and thus decision was made to discontinue the observation in January 2011. Nevertheless, the SMILES observation has revealed the new aspects of global atmosphere on account of its precision at a level 10 times or more, which is higher than that of conventional systems. Here we introduce some initial results. SMILES is performing the spectroscopic observation with limb geometry; the tangent height ranges from-10 km to 100 km. Figure 2 shows example spectra of SMILES spectrum. These spectra thus obtained with complete absence of ripples were so beautiful that they led us to mistake them for some simulation results. The initial data given in October 2009 were, at every occasion when introduced at international meetings, evaluated with such words of respect and praise as "Impressive! Japanese Technology!" by associate researchers. This fact led us to be convinced of the technical capabilities at a high level of our …
