The method includes detecting an intensity of a reflective light according to a wavelength of a light as spectrum data for each wavelength, converting the detected spectrum data for each wavelength into a spectrum value as a function of a wavelength that a refractive index is reflected, and detecting a position where the intensity of the reflective light has a peak as a thickness of a spacer layer and a cover layer respectively by converting the converted value into a length of an interference area for representing a layer thickness of the optical disc by the Fast Fourier Transform. The disclosed method has advantages for high precisely measuring thickness of an optical disc.

摘要： Disclosed herein are a platinum-based catalyst for oxidation/reduction reactions and the use thereof. The platinum-based catalyst is prepared by loading a catalyst composition comprising a water soluble salt of at least one metal selected from among cerium (Ce), zirconium (Zr) and rhenium (Re), on a support comprising at least one selected from among alumina, silica and titania. The disclosed catalyst can be prepared in a simple manner without any particular limitation as to the kind of usable water soluble platinum salt, and when it is applied to various oxidation reactions, including water gas shift reactions of carbon monoxide, three-way catalytic reactions, and selective oxidation reactions of carbon monoxide, and to reduction reactions, such as reactions of removing nitrogen oxide (NOx), it will show excellent catalytic activity. In particular, the disclosed catalyst shows excellent performance even in a specific temperature range in which it is difficult to apply the prior high-temperature water gas shift reaction catalyst and low-temperature water gas shift reaction catalyst. Also, it can remove carbon monoxide even at high temperatures without the loss of hydrogen caused by methanataion, and thus is particularly useful in a hydrogen production process of producing high-purity hydrogen for fuel cells.
