| Abstract: | In this paper a kind of visible-near infrared Fourier transform spectrometer developed byour laboratory is described. The He-Ne laser reference system is used for sampling the interfe- rogram at equal interval of retardation. Increments of 158.2nm in optical path length are obt-ained by subdividing the natural fringe spacing of He-Ne laser by a factor of 4. The workingwavelength range is between 400--1000nm. The Apple-2 microcomputer is used for instrumentoperation controlling, inte.ferogram sampling and data processing. The instrumental performanceis demonstrated and aliasing problem is discussed by spectral measurement. |
