Abstract

Digitally recorded spectra containing lines of width less than or equal to the resolution at which the measurement has been made are observed to show some photometric error. In spectra measured by Fourier transform spectroscopy, this error may be substantially reduced if the interferogram is aero-filled. To prevent the generation of artifacts in the spectrum (of a similar origin to the sine x side-lobes formed when a non-zero-filled spectrum is computed with a box-ear truncation function), the aero-filled interferogram must be suitably apodized.
