Title: Beam splitter assembly with output insensitive to polarisation changes
Inventor: DECKER DEREK E
IPC: G02B27/28
Filed: 1997-07-18
Abstract: The beam splitter assembly comprises thirteen beam-splitter cubes arranged to provide said six polarization-balanced output beams, each cube containing a partially reflective surface, such that light beam incident on said partially reflective surface is split into transmitted and reflected light beams. The transmitted light beam contains a first portion of said s-component polarization and first portion of said p-component polarisation, and said reflected light beam contains a second portion of said s-component polarisation and a second portion of said p-component polarization.  Each cube contains a plane of incidence defined by the incident light beam and the reflected light beam, and each of said six polarization-balanced output beams pass through two pairs of polarization-balanced beam-splitter (PBBS) cubes selected from said thirteen beam-splitter cubes. Each of said pairs of PBBS cubes have orthogonal planes of incidence relative to the incident light beam, and the light beam passing through each of said pairs of PBBS cubes is either transmitted by both PBBS cubes or reflected by both PBBS cubes. The beam-splitter cubes are 50 percent beam-splitter cubes. The six polarization-balanced output beams are of equal intensity.

Inventor: DEVOS PHILIPPE
IPC: D06C7/02
Filed: 1998-09-10
Abstract: In the production of a polyester fabric, where all the fibers have an elastic stretch, a proportion of the fibers are a bi-component type which can be shaped into spiral coils. The fiber preparation and spinning stages are for non-stretch filaments, and the fabric is strongly structured to take in its potential elasticity. For the production of a polyester fabric, where all the fibers have an elastic stretch, a proportion of the fibers are a bi-component type which can be shaped into spiral coils. The fiber preparation and spinning stages are for non-stretch filaments, and the fabric is strongly structured to take in its potential elasticity. The loomstate fabric is given an initial heat treatment in hot air at a temperature of 180-190 degrees C under a low fabric tension before conventional processing and finishing such as washing and dyeing. During all subsequent heating processes, the fabric tension is limited. For the initial heat treatment, the fabric is carrier by a stenter through a temperature of 185 degrees C for 1.0-1.5 minutes. The fabric is composed of polyester and wool fibers, in a 50:50 mixture, where all the polyester fibers have a bi-component structure. The stenter gives a stenter advance of 15% and a fabric width control at the stenter exit of 9% less than the width of the loomstate material. After dyeing, the fabric is dried at a stenter at a temperature of 130 degrees C after a heating stage at 185 degrees C. The fibers are mixed at the carding and spinning stages, without recombing. The polyester and wool fibers are taken from their bales, to be mixed by carding and combing to form tops followed by drawing at a drafting frame and spinning. During weaving, the warps are reduced by 15-20%. The bi-component polyester fibers have an elastic stretch of 15-20% in the warps and wefts. The cloth is composed of yarns number 2/70, in the warps and wefts. The bi-component polyester fibers are in two different cuts of 80 and 105.
