scientist, pioneer of Fourier transform spectroscopy, expert in physical instrument design, numerical methods as applied to spectroscopy, and in atomic and molecular spectroscopy
Brault (February 10, 1932 – November 1, 2008) was a 20th-century scientist and a pioneer of Fourier transform spectroscopy.
He was a world-leading expert in physical instrument design, numerical methods as applied to spectroscopy, and in atomic and molecular spectroscopy.He graduated from Princeton University in 1962 as a student of Robert H.
Dicke on the gravitational redshift of the sun and worked later at the Kitt Peak National Observatory, where he installed a high-resolution Fourier transform spectrometer used for astronomy, solar physics, and laboratory spectroscopy.
In his early years, Brault was involved in the development of the lock-in amplifier, and of differential interference microscopy and phase modulation microscopy with Robert D.
