Abstract : The degradation due to random segment jitter and phase mismatch on the average far field, on axis irradiance of a laser beam transmitted from a telescope with a segmented primary mirror is computed. The derived expression is exact within the stated assumptions and offers a more accurate alternative, for this application, to the commonly used Strehl approximation.
