Abstract
A dispersive compact Fourier transform spectrometer is realized which operates in the visible wavelength range. No moving parts, no imaging system and compactness are die characteristics of this spectrometer. It is based on a novel beam splitter design, which reduces the influence of the size of the light source and therefore the spatial coherence requirements. The effect of dispersion due to an asymmetric configuration is described. A mathematical correction to get rid of eventual mirror distortion is reported. Finally, some considerations on noise and a method to reduce its influence are presented. A resolution of 3nm was measured at 633nm.
