title: High-luminosity visible and near-IR Fourier-transform photoacoustic spectrometer.
abstract: A visible and near-infrared (0.36-3-microm) Michelson interferometer has been built to perform Fourier transform photoacoustic spectroscopy. The scanning (step and integrate) and the internal modulation are obtained with only one active element: the moving mirror holder driven by a linear motor. The signal-to-improvement and the performance of the spectrometer are compared with other photoacoustic methods and illustrated by various spectra.
