A collimating lens is generally used in the optical system of polarized birefringent interferometer with a Wollaston prism (WP) as a multichannel Fourier transform spec-trometer (MCFTS). In this time, we designed a new optical system of WP interferome-ter without collimating lens. A smaller WP is available as a MCFTS in the system.
Interferograms of several discharge lamps were obtained using this system. Line spectra were reproduced after FFT procedures for the interferograms. Various applications are suggested utilizing the merit of this compact and inexpensive MCFTS system.
