In this paper within introducing several metrics, has obtained effects of one especial aberration like coma with different amplitudes. Also, result of spherical aberrations changes on increasing or decreasing of metrics have found and compared them. Finally, effects of random aberrations on beam and image have shown and calculated magnitude of the square of intensity metric for them.
