The conditions of sparkle contrast measurement which were not affected by the modulation of display matrix image itself were investigated in the viewpoint of optical imaging. The proposed method utilizing diffraction blur by the circular aperture of imaging lens enabled to get accurate, reproducible, comparable data within the proposed conditions.
