Abstract
Starting with the Dini expansion of a wave aberration function, a relationship is derived between the Maréchal evaluation of the Strehl definition (MESD) for uniformly illuminated aperture and the MESD for an aperture with nonuniform intensity transmission. The result is particularly useful for rapid evaluation of the far-field peak-intensity degradation due to aberrations and in problems connected with aberration balancing techniques, as well as for the estimation of optical system performance when the aperture intensity distribution is varied.
