- 論文の詳細を見る
A concept of heterodyne spectroscopy for absorption measurements which employs a broadband short-pulse laser is presented. The absorption line structure of the sample in the spectral width of a short-pulse laser is measured with broadband heterodyne detection. The absorption spectrum can be measured, in principle, with a single laser shot, and the method is potentially useful for laser long-path absorption measurements of atmospheric trace species. Application to an airborne laser long-path absorption system for measuring CH_4 is discussed.
