Abstract AR
استخدام حلول عددية ذات بعدين لتقييم كفاءة الفتحات المعرقلة للضوء من خلال دراسة تأثيرها على حدود قدرة التحليل.
تضمن البحث حساب معدل شدة و عرض دالة الانتشار النقطية، معدل مركبة الترددات لدالة التضمين الانتقالية و كذلك معدل الحلقات الجانبية لصورة زوج من الخطوط.
النتائج أوضحت أن الفصل بين الخطين يصبح سويا عند استخدام نصف قطر الإعاقة المركزية أكبر أو يساوي تقريباً 0.6 مرة من نصف قطر الفتحة الأصلية.
Abstract EN
Two-dimensional numerical solutions are carried out to assess the quality of obstructing apertures in terms of the diffraction limited resolution.
This include the quality of the point spread function (psf), the modulation transfer function (MTF), and an image of double lines.
These are average intensity of the psf (AI), maximum intensity of the psf, (MI), full width at half maximum of the psf (FW) average frequency components of MTF (AFC), and average side loops of an image of a double lines.
The results indicate that the separation of the two lines becomes recognizable using central obstruction of radius equal to or greater than approximately 0.6 times the radius of the primary aperture.
