Fourier transform spectrometer, method of making a Fourier transform spectrometer and method of displaying an electromagnetic spectrum

摘要

The invention relates to a Fourier transform spectrometer (100) comprising a diffuser element (102) for diffusing light, a first polarizer element (104) for polarizing light exiting the diffuser element (102), a birefringent splitting element (106) for splitting light emerging from the first polarizer element (104) into differently polarized radiation beams, a second polarizer element (112) acting as an analyzer for polarizing radiation beams emerging from the splitting element (106) and a detector element (114) for detecting radiation from the second polarizer element (112) leaking light. In this case, the first polarizer element (104) and the second polarizer element (112) use different polarization methods.
