翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Spectral resolution ： ウィキペディア英語版 Spectral resolution The spectral resolution of a spectrograph, or, more generally, of a frequency spectrum, is a measure of its ability to resolve features in the electromagnetic spectrum. It is usually denoted by $\backslash Delta\backslash lambda$, and is closely related to the resolving power of the spectrograph, defined as $R\; =$, where $\backslash Delta\backslash lambda$ is the smallest difference in wavelengths that can be distinguished at a wavelength of $\backslash lambda$. For example, the Space Telescope Imaging Spectrograph (STIS) can distinguish features 0.17 nm apart at a wavelength of 1000 nm, giving it a resolution of 0.17 nm and a resolving power of about 5,900. An example of a high resolution spectrograph is the ''Cryogenic High-Resolution IR Echelle Spectrograph'' (CRIRES) installed at ESO's Very Large Telescope, which has a spectral resolving power of up to 100,000.〔(- CRIRES Instrument page at ESO )〕 ==Doppler effect== The spectral resolution can also be expressed in terms of physical quantities, such as velocity; then it describes the difference between velocities $\backslash Delta\; v$ that can be distinguished through the Doppler effect. Then, the resolution is $\backslash Delta\; v$ and the resolving power is $R\; =$ where $c$ is the speed of light. The STIS example above then has a spectral resolution of 51 km/s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spectral resolution」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
