Abstract AR
في هذا البحث وضع تصميم جديد لقرص التضمين البصري الكسوري باستعمال تكرار جديد للدالة الكسورية، و تم تحليل النتيجة عن طريق حساب دالة الانتقال الضمني، و ذلك بالمقارنة مع نتائج قرص التضمين البصري العادي.
و قرصا التضمين البصري العادي و الكسوري عبارة عن قرص دائري ذي نصف قطر يساوي 9cm، و كل منها يتكون من 20 مقطعا، عشرة منها مضيئة و الأخرى مظلمة.
و قرص التضمين الكسوري يحتوي على أنموذجين الأنموذج الآخر يستعمل للكشف عن الهدف، و الأنموذج الأول يستعمل للقفل على الهدف.
و أفضل تشابه لسلوك دالة الانتقال الضمني بين قرصا التضمين الاعتيادي و الكسوري كان عند نهاية القرص العادي.
كذلك فأن القدرة النافذة من القرصين تعتمد على حجم بقعة الليزر الساقطة و حجم المقطع الكسوري.
و إن التناسب بينمها طردي.
Abstract EN
The purpose of this paper is to evaluate the error of the approximation of an entire function by some discrete operators in locally global quasi-norms (Lð, p-space), we intend to establish new theorems concerning that Jackson polynomial and Valee-Poussin operator remain within the same bounds as bounded and periodic entire function in locally global norms (Lð, p), (0 < p ≤ 1).
In this paper it was designed a new fractal optical modulation by using a new iteration of fractal function, the result was analyzed by MTF evaluation, and it compared with results of normal optical modulation.
The normal and fractal optical modulator is a circular disc which has a radius R = 9cm, both of them consist of twenty sectors, ten sectors are opaque and the other ten sectors are transmitted for the light.
The fractal optical modulator contains two patterns, the pattern two can be used to detect the target, and pattern one can be used to lock the target The best similarity of MTF behavior for normal and fractal Reticle was evaluating the power transparent depends on the size of the laser spot and the size of the sector, where the proportionality between them is directly.
