Alignments of Focus-lens, recording media, and CCD camera positions are studied. Several rectangle patterns were displayed in SLM and captured by CCD camera. Fourier transform of captured rectangle patterns were calculated and the magnitude of the third order in spatial frequency was picked up with changing the position of the focus-lens. This signal was in good agreement with the signal-to-noise ratio and useful method in holographic data storage.
