Polarization aberrations in the optical microscope
Annual Meeting Optical Society of America, 1988A long-standing problem in polarized light microscopy has been the inability to achieve simultaneously high spatial resolution and high contrast due to the rotation of the plane of polarization at oblique interfaces between crossed polars. In such cases, the system is highly astigmatic and produces severely degraded images.

Polarization aberration in resource satellite system
SPIE Proceedings, 2005Polarization aberration is one of the most important factors affecting the performance of optical systems, especially in systems which have many reflectors. The polarization response characters of the reflectors will change the polarization state of the incident light and the polarization aberration will affect the imaging quality of the system.

Polarization aberrations of laser radiation
Optics and Spectroscopy, 2000Polarization aberrations (PAs) of laser radiation, defined as distortions of the wave-polarization characteristics, are considered within the framework of wave theory. The parameters describing these aberrations are introduced. It is established that PAs already appear in the paraxial region.

Adaptive measurement and correction of polarization aberrations
Adaptive Optics and Wavefront Control for Biological Systems V, 2019We present the concept of adaptive polarization optics and validate it using a system that contains full polarization control and measurement at pixel level. Polarization control is implemented based on double pass spatial light modulator (SLM) system while the measurement is realized via an imaging Stokes polarimeter. Our design is able to extract the

Technique to manage polarization aberrations
Optical Review, 2009Optimizing the polarization characteristics of an optical system is generally a complicated problem, unlike the case of optimizing scalar characteristics such as pupil function. Here, we will propose a linear approximation approach to solve this problem systematically and define the conditions to be satisfied to make the approximation accurate.

Polarization aberration measurement of lithographic tools
Optical Metrology and Inspection for Industrial Applications V, 2018The NA of immersion lithography has reached 1.35, in which case polarization effect must be taken into account. The performance of the projection lens should be characterized by polarization aberration. We proposed a polarization aberration measurement theory and method, using the binary grating structure as the mask pattern, with intensity ...

Polarization aberration analysis in lithographic tools
Optical Engineering, 2019Hypernumerical aperture and polarized illumination are the key technologies of resolution enhancement of lithography. When the numerical aperture reaches 0.85 and above, especially in the immersion lithography, polarization effect must be taken into consideration. The performance of the projection lens needs to be characterized by rigorous polarization

Overcoming Polarization Aberrations In Microscopy
SPIE Proceedings, 1988A long-standing problem in polarized light microscopy has been the inability, due to polarization aberrations, to achieve simultaneously high spatial resolution and high contrast. The rotation of the plane of polarization at oblique interfaces between crossed polars causes the pupil function to resemble a dark cross rather than being uniformly dark ...

Calculation of polarization aberrations by the method of polarization-wave matrices
Optics and Spectroscopy, 2007The technique of calculation of polarization aberrations with the help of the method of polarizationwave matrices is proposed. Radiation is represented as a coherent set of the Hermitian-Gaussian modes with a certain amplitude, phase, and polarization state; the longitudinal component of the field is also taken into account.

Experimental observation of the aberration effects on a radially polarized beam
Journal of the Optical Society of America A, 2016In the last couple of decades the radially polarized beam has been gaining a lot of importance in diverse areas owing to its unique properties, especially near the focus of a lens. For instance, when focused tightly, the radially polarized beam produces a strong axially polarized field on the optical axis near the focus.
