Point Spread Function of Optical Systems Apodized by Semicircular Array of 2D Aperture Functions with Asymmetric Apodization
The simultaneous suppression of sidelobes and the sharpening of the central peak in the process of diffraction pattern detection based on asymmetric apodization have been investigated. Asymmetric apodization is applied to a semicircular array of two-dimensional (2D) aperture functions, which is a series of ‘coded-phase arrays of semicircular rings randomly distributed over the central circular ...
متن کاملPoint 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...

متن کاملAnalysis of the asymmetric apodization using the fractional Fourier transform
The e ect of asymmetric apodization is analysed using the fractional Fourier transform. The focusing properties of an apodizing pupil mask are investigated by means of a simple display in a generalized phase-space (or x±p domain). Some comparative computer simulations are performed and curves displaying the Strehl ratio versus defocus are presented in order to illustrate the possibilities of o...
متن کاملProgrammable vector point-spread function engineering.
We use two nematic liquid crystal spatial light modulators (SLM's) to control the vector point spread function (VPSF) of a 1.3 numerical aperture (NA) microscope objective. This is achieved by controlling the polarization and relative phase of the electric field in the objective's pupil. We measure the resulting VPSF's for several different pupil field polarization states. By using single fluor...
