چکیده
In this paper, we have studied the aberrated images of coherently illuminated straight edge objects with annular aperture in the presence of apodisation. The analytical studies were made for annular apertures apodised with Shaded aperture under the influence of defocus and primary spherical aberrations. The effect of aperture obscuration and apodisation on the edge ringing and peak intensity has been considered.

Point Spread Functions Of Aberrated Optical Systems With Annular Apertures
Annular apertures are derived for the rotationally symmetric optical systems. Shaping the point spread function in terms of the magnitude of the radius of its first dark ring in comparison to that of Airy case is one of the prime merit functions associated with super-resolved point spread functions. Our studies entail in the estimation of the radius of the first dark ring in the obtained diffra...

The point spread function (PSF) of aberrated optical system apodized with Hanning and Lanczos amplitude filters has been determined. The influence of phase mask also considered for various zones of the aperture. For this study rotationally symmetric coherent optical system has been considered. INTRODUCTION Coherent illumination of the object is essential in order to get narrow bandwidth spectra...
متن کاملBuckling Analysis of Polar Orthotropic Circular and Annular Plates of Uniform and Linearly Varying Thickness with Different Edge Conditions
This paper investigates symmetrical buckling of orthotropic circular and annular plates of continuous variable thickness. Uniform compression loading is applied at the plate outer boundary. Thickness varies linearly along radial direction. Inner edge is free, while outer edge has different boundary conditions: clamped, simply and elastically restraint against rotation. The optimized Ritz method...
متن کاملCharacteristics of Electromagnetic Pulse Coupling into Annular Apertures
Electromagnetic pulse (EMP) coupling into the annular apertures can disturb or damage much electronic equipment. To enhance electronic system’s capability of anti-electromagnetic interference, the finite difference time domain method (FDTD) was employed to study the characteristics of electromagnetic pulse coupling into the cavity enclosures with annular apertures. The coupling characteristics ...
متن کاملMode-Matching Analysis for Circular and Annular Aperture Scattering
The mode-matching applications to scattering from circular and annular apertures in a thick perfectly conducting plane are reviewed. The Hankel and Weber transforms are utilized to solve the boundary-value problems of circular and annular apertures. Simple electrostatic problems are presented to illustrate the mode-matching method in terms of the Hankel and Weber transforms. Various types of We...
