Abstract

The modification in the imaging characteristics, achieved by employing linear polarisation masks at different zones of the optical system is considered. This modification technique is comparatively easy to realise into practice. The imaging characteristics of the optical system employing linear polarisation masks illuminated with partially polarised light in terms of point image intensity distributions by making use of coherency matrix approach is studied. The effect of degree of polarisation and polarisation from of the incident light and relative sizes of the three zones, and orientation of the linear polarisation masks has been considered.
