Abstract
From optical image evaluation point of view Strehl ratio is an important quality criterion. It has direct relation with the image formation process. Strehl ratio is commonly defined as the ratio of image irradiance at the diffraction focus with apodisation to one without apodisation. For small aberrations, Strehl ratio is an approximate measure of the fraction of the diffracted radiant flux that is concentrated in the central bright core at the image of the point object. The Strehl ratio maximizing means increasing the brightness of the image. Several researchers have investigated and developed various methods to maximize its value. Strehl ratio is not a physically measurable quantity;
