​Fourier Transform Spectroscopy (FTS)

  • Novel interferometer design: imaging FT spectrometers, spatial-spectral interferometry, stationary interferometers, spectrometers on a chip, stationary-wave integrated FT spectrometers.
  • Instrument design, scientific objectives, and measurement results for space missions utilizing Fourier transform spectrometers
  • Laser frequency combs for Fourier transform spectroscopy: development of frequency comb sources and instruments, dual-comb spectroscopy, frequency-comb based spectroscopy with Michelson interferometers or pulse shapers. Applications to laboratory spectroscopy and to sensing.
  • Laboratory spectroscopy: advanced light sources and measurement techniques for Fourier transform spectrometers. FTS at synchrotron facilities, nano-spectroscopy, nonlinear and multidimensional FT spectroscopy with ultrashort pulse lasers.
  • FTS applications:  industrial process monitoring, spectroscopy, Earth and planetary science, atmospheric remote sensing, trace gas detection, FTS at astronomical facilities.
  • FTS algorithm developments: spectral and radiometric calibration, instrument line shape modeling and correction, nonlinearity effects.
  • All other topics related to instrument developments and characterizations, data processing, and applications of Fourier transform spectroscopy.
