In this paper, we evaluate the effect of geophone configuration on dispersion image for linear spreads in the MASW method. To reveal the spectral resolution of dispersion images, MASW records were collected using nine different types of linear spread configuration, then dispersion image for each record were calculated usii lysis technique, and were compared to present preferable linear spread type for a MASw survey. The results show that, better dispersion image resolution and dispersion curve in the wide frequency range can be obtained by using an SL-type geophone configuration. Besides this, in a survey in which higher frequencies are more important, an SII-type configuration may be preferable. With the SII-type spread configuration, the fundamental mode can easily be distinguished from the higher modes.
