Stationary-wave integrated Fourier-transform spectrometry

Stationary-wave Integrated Fourier-transform Spectrometry (SWIFT) is a sophisticated spectroscopic technique developed to analyze the spectral properties of light, particularly in measuring absorption and emission spectra. This method combines principles of both stationary wave phenomena and Fourier-transform techniques to enhance the sensitivity and resolution of spectral measurements. ### Key Concepts: 1. **Stationary Waves**: In the context of optics, stationary waves refer to wave patterns that remain fixed in space due to the interference of two waves traveling in opposite directions.
