The fleight target painted with moire pattern to be tracked by a high speed camera through a transparent grid give us a very high precision method for the measurement of target displacement. The film unflatness, air fluctuation and the vibration of the high speed camera are also effected on the shape change of the moire. The small amount change of the pitch, yaw, rotation and the direction of the fleight target can be easily measured by this method.
