Abstract
During the process of imaging in interference spectrum, apodization is an important part of the spectrum reconstruction in imaging Fourier transform spectrometer (IFTS), and it has a powerful effect on the accuracy of reconstructed spectra. This paper analyzes the principle of apodization, and uses six common kinds of apodization functions to process the simulated interferogram. Combining with the principle of selecting apodization functions, analyzing experimental results by approaches of comparison and drawing conclusions. The conclusions show that Happ-Genzel function is best for simulated interferogram, and the experiment shows that stand or fall of selecting apodization functions impacts directly on the accuracy of reconstructed spectra.
