Abstract

Beamsplitter is a crucial element of the Fourier spectrometer. In conventional form it is composed of two identical wedge plates reducing ghost reflections influence. Simultaneously, it can introduce the most significant spectrum errors in the reason of improper quality or misalignment. The influence of geometrical parameters of both wedge plates on measured spectrum is presented. The paper contains numerical analyses for assumed and real object spectrum. Additionally the dependence between incident wave shape and quality of reconstructed spectrum is considered.
