Performance of a polarization-masked lens aperture in the presence of spherical aberration

DR Chowdhury, K Bhattacharya, S Sanyal… - Journal of Optics A …, 2001 - iopscience.iop.org
This paper suggests the possibility of partial compensation of spherical aberration with a
polarization-masked lens aperture. The principle is based on the fact that any pre-specified …

Transverse or axial superresolution with radial birefringent filter

M Yun, L Liu, J Sun, D Liu - JOSA A, 2004 - opg.optica.org
The superresolution technique is well known for its ability to compress the central diffraction
spot to a size that is smaller than the Airy diffraction spot. The radial birefringent filter, which …

Vector wave imagery with a lens masked by polarizers

K Bhattacharya, A Ghosh… - Journal of Modern …, 1993 - Taylor & Francis
The optical transfer function (OTF) of an imaging system using polarization devices depends
in general on the state of polarization of the input beam. In fact, the 'amplitude point spread …
