We report on our work on producing liquid crystal switchable modal lenses and their use in a
compound lens system in order to produce variable focus/zoom lenses. We describe work …

In this paper, we study the focusing of a stochastic electromagnetic beam by a bifocal lens.
By taking the electromagnetic Gaussian Schell-model (EGSM) beam as an example, the …

The equivalent air gap method is a simple way to trace the ray propagation in an isotropic
medium, but it cannot be applied to an anisotropic medium. We present the exact general …

This paper reports the imaging characteristics of an optical system consisting of a lens made
of a uniaxial birefringent crystal sandwiched between two linear polarizers under …

We study the intensity point spread function (IPSF) of a uniaxial birefringent lens
sandwiched between two linear polarizers under broadband illumination having flat-top …

Polychromatic or white-light optical transfer function (OTF) is put forward as a criterion to
evaluate the performance of a uniaxial birefringent lens sandwiched between two linear …

This report forms a part of the systematic investigation on the imaging behaviour of an
optical system consisting of a lens made of a uniaxial birefringent crystal sandwiched …

A uniaxial birefringent crystal lens with its optic axis perpendicular to the system axis and
sandwiched between two properly oriented linear polarizers behaves as an isotropic lens …

Plastic optics are seeing increased usage in various imaging and non-imaging applications
due to its low cost, ease of manufacturing and complex parts assembly. Non-imaging …
