In this paper we tried to investigate the Defocusing role in CCD modulation transfer function measurement. To calculating the MTF, point spread function was measured. In experiment, we used a 3W LED with warm white spectra as the broadband source. Finally the effect of the lens relocation on CCD MTF and its cut-off frequencies studied.
