The incoherent of a periodic point object consisting of equidistant unit impulses is considered in this study. An aperture composed of black-with concentric annuli is utilized. The intensity distribution in the imaging plane is calculated from the convolution product of the object intensity and the impulse response appropriate to the system. An expression of the modulation transfer function of the imaging system is deduced in matrix from. A computer program is constructed to complete the normalized autocorrelation function of some black-white apertures and compared with that obtained for a uniform circular aperture.
