High‐Speed Spectroscopy: High‐Speed Fourier‐Transform Infrared Spectroscopy with Phase‐Controlled Delay Line (Laser Photonics Rev. 15(1)/2021)

In article number 2000374, Kazuki Hashimoto, Venkata Ramaiah Badarla, and Takuro Ideguchi develop a high-speed Fourier transform infrared spectroscopy technique called phase-controlled infrared spectroscopy (PC-FTIR) that allows for measuring broadband MIR absorption spectra of molecules at a rate of above 10 kHz. This technique is to be particularly useful for measuring fast irreversible phenomena and acquiring a large amount of spectral data within a short time.
