Study of resolution power and intensity distribution for optical system using synthetic square aperture

Abstract EN

In this research effect of square synthetic aperture (apertures are distributed alternately as checker board) has been studied on intensity of the line object in comparison with square aperture for ideal optical system or contain focus error (W20 = 0.5λ, 1λ, 2λ) or spherical aberrations (W40 = 0.5λ, 1λ) or coma aberrations (W31 = 0.5λ) with rotation angle (ψ= 0, 90, 180) The total number of sub apertures are depending on number of rows and columns in square synthetic aperture and the numbers of rows and columns have been chosen are similar which values are (T=2,4,6,8,10) The results showed that increasing the number of synthetic sub apertures lead to increasing resolution power in ideal optical system and increasing intensity whatever the aberrations amount was high in the optical system and so work to decrease the secondary peaks in the intensity distribution of line image.
