Abstract :
A Fourier-transform spectrometer has been developed that can simultaneously determine the amplitude and the phase spectrum. It is based on the interference of two coherent frequency-comb beams and uses no moving part. As its first application, the complex transmission of free-standing metal wire materials is measured at varying, precise incidence settings.
