We show how to two dimensionally encode the polarization state of an incident light beam
using a parallel-aligned liquid-crystal spatial light modulator (LCSLM). Each pixel of the …

An imaging system and method are presented. The system comprises an imaging lens unit,
an imaging detector, and a birefringent element located between the imaging lens unit and …

The coordination polymer Pb (H2O)[Au (CN) 2] 2 (1) was synthesized by the reaction of KAu
(CN) 2 and Pb (NO3) 2. The structure contains 1-D chains of lead (II)− OH2 linked via Au …

The Strehl definition along the axis of a birefringent lens sandwiched between two polarizers
is studied analytically. The optic axis of the birefringent lens made of a uniaxial crystal is …

We present a novel configuration for a twisted-nematic liquid-crystal display (TN-LCD) that
makes it operate as a controllable polarization rotator. We extend a previously reported …

We show experimental results for programmable polarization multiplexing of diffractive
optical elements (DOEs) onto two liquid-crystal displays (LCDs). The first LCD encodes the …

In this paper we present a simple approach to obtain extended depth of field for any optical
imaging system just by adding a birefringent plate between the lens and the detector. The …

A method of designing a lens with an extended focal depth is studied. The lens is a
cemented doublet composed of a birefringent lens and a conventional lens. The crystal …

Anisotropic diffraction gratings based on a holographic polymer-dispersed liquid crystal
(HPDLC) are realized by interferometric exposure using a spatial light modulator (SLM). The …
