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.

Fourier transform spectrometers onboard satellites looking toward Earth provide new insights on the planet’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 the cosmic diffuse infrared and microwave background radiation. Ground-based and airborne FT interferometers explore a variety of topics in physics, geophysics, and astrophysics, including solar processes, radiative energy transport in the atmosphere, the geographic distribution of greenhouse gases and air pollutants, and spectroscopic studies using the atmosphere as a natural laboratory. 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
