Recognition of Some Modulated Apertures Using the Cascaded Fabry- Perot Interferometer(CFPI)

A.M. Hamed

Abstract

In this paper, five modulated apertures are considered. The first has linear distribution, the second has conic shape, the third has quadratic distribution, the fourth has Gaussian distribution, and the fifth has B/W concentric annuli. These apertures are recognized from the fringe shift occurred in the interferometric images using the CFPI. The recognized modulated apertures are compared with the fringe shift corresponding to the uniform circular aperture. The improved multiple beam Interferometer or the CFPI working in transmission is considered for the aperture recognition. The sharp interferometric images obtained from the CFPI provided with the apertures are constructed using MatLab code.

Keywords
