□ The Korean researchers opened the possibility of developing small-sized spectroscope* of nano-resolution that is used in appraising jewelry and cultural assets, detecting drugs, and analyzing the purity of medicines. If researchers replace high-priced filters used in the existing spectroscope with low-priced random filters, it is expected to contribute to miniaturizing spectroscopes.

(*spectroscope: measures the intensity of light’s wavelengths coming out from objects and shows the information in graphs. Measuring equipment that is widely used throughout the industries, including modern optics, chemistry, and ocean engineering)

○ This study, which was led by professor Heung No Lee at Gwangju Institute of Science and Technology (GIST, President   Young Joon Kim) and participated by Dr. Oliver and Woong Bi Lee, was carried out with the support of medium-sized research support program being implemented by the Ministry of Science and Technology (Minister: Joo Ho Lee) and the National Research Foundation of Korea (President    Seung Jong Lee). The study was published in the prestige press in the field of optics Optics Express on February 12, 2013. It is not common for a long thesis of 22 pages to be introduced in Optics Express. (Title of thesis: Filters with random transmittance for improving resolution in filter array based spectrometers)
