| Outline of Final Research Achievements |
Infrared synchrotron radiation is a high brilliance light source and the feature plays an effective role in micro-optical spectroscopy. The noise level of an infrared synchrotron spectrum, however, sometimes is higher than that of thermal radiation spectrum. The higher noise level make it difficult to detect small signal from, for example, organic thin film. In this study, we investigate the source of the noise case of the synchrotron radiation source, and a saturation of an infrared detector is shown to be one of the most important noise sources. The detector is a typical infrared HgCdTe (MCT) detector. In order to improve the noise level, optical filters that confine wavenumber range are found to be effective. Using these method, we try to detect the absorption change of an organic samples in a liquid cell.
