Fourier Transform Spectroscopy


The OSA Fourier Transform Spectroscopy (FTS) Topical Meeting focuses on the latest advances in instrumentation and applications of FTS to astronomy and astrophysics, atmospheric science and remote sensing, laboratory spectroscopy, analytical chemistry, bio-medicine, and a variety of industrial applications. 

Today, Fourier transform spectrometers onboard satellites looking downwards provide new insights on the Earth's atmosphere, climate, and a host of other meteorological and remote sensing applications. Instruments looking out provide a wealth of data targeting galaxies, stars, planets, and many smaller objects within the universe. Ground-based FT interferometers explore a variety of astrophysical and terrestrial fields including the global geographic distribution of CO2 sources and sinks. Chip-scale interferometers fabricated using state-of-the-art nanotechnology open up new opportunities for space and industrial applications. Laser frequency combs dramatically improve the resolution and recording speed of Fourier spectrometers. New spectral regions (e.g., VUV or THz) are under exploration with synchrotron radiation. Ultrashort laser pulses expand the territory of FTS to nonlinear and multidimensional spectroscopy. This international conference will provide a unique opportunity to discuss many of these exciting developments in a strongly interdisciplinary environment.
