تصميم مرشح فابري - بيرو باعتماد الربط بين نظريتي الطبقة المكافئة والمصفوفة المميزة المعدلة

Design of narrow bandpass Fabry - Perot interference filter for the thermal region (8-14 um) especially at co2 laser wavelength (10.6 um) by the connection between two theorems: equivalent layer and the modified characteristic matrix theory. Results shows that the region of stop band surrounding the passband peak were extended, theiefore, no necessity required for glass or absorption filters
