The hyperfine structure (HFS) constants of 32 levels in Lu I and 10 levels in Lu II were measured by fitting Fourier transform spectra, of which 25 Lu I levels and 4 Lu II levels are reported for the first time to our knowledge. The experimental data obtained in this paper is an extension of the atomic HFS data of Lu element and increase the number of levels with known HFS constants of Lu I and Lu II to 74 and 24 levels.
