Single-Beam을 이용한 광음향 분광법에 관한 연구
A Study on Single-Beam Photoacoustic Spectroscopy
초록
A new type single beam photoacoustic spectrometer suitable for measuring optical absorption of condensed powder matter with the automatic calibration capability of a source power spectrum is introduced. The signal processing until of this spectrometer consists of a photoacoustic cell a lock-in amp., a switching circuit and a personal computer. The measured optical absorption spectra of a few material by this method are good agreement with the results obtained by the double-beam photoacoustic spectrometer.
