Updated at May 1, 2013 QMI(Quantum Measurement & Instrumentation) is a cutting-edge laboratory will understands light scientifically. Scientific challenges of QMI Development of new light sources, and their application to (1) highly precise observation or measurement of sample surfaces. Scientific study of interaction between light and matter. Keywords relating to QMI optical near-field, surface plasmon resonance, extreme ultra-violet light, water-window x-ray, point diffraction interferometry, nanoscale science, 3D EM-analysis
QMI lab. has been studied "light" scientifically. Radiation and detection of light is interaction between photon and electron. Therefore we are studying about quantum. It has long been suspected that observation of small world by illumination of light is impossible because of diffraction limit of light. But such scientific common sense die out with the advent of Scanning Near-field Optical Microscope (SNOM). Members of QMI lab. challenges themselves to apply　”light" to state-of-the-art "Mono-dukuri" technology by (1) SNOM having 2nm lateral resolution, 10nm vertical resolution, (2) PS-PDI interferometer having measurement accuracy of sub-nm, (3) light scattering method having high detection sensitivity for tiny defect at few tens of nm, (4) EUV light source by laser-produced plasma having intense pulse light at 13.5 nm. Wonderful and fantastic nano world will gives us strange and incredible behavior of light and electron with their interactions. Such phenomena will encourage us to break new ground for creation of new technology.
