摘要： The present invention relates to x-ray diffraction measurement by using moving x-ray source x-ray diffraction. The invention comprises a raster-scanned x-ray source, a specimen, a collimator, and a detector. The x-ray source is electronically scanned which allows a complete image of the x-ray diffraction characteristics of the specimen to be produced. The specimen is placed remote from the x-ray source and the detector. The collimator is located directly in front of the detector. The x-rays are diffracted by the specimen at certain angles, which cause them to travel through the collimator and to the detector. The detector may be placed in any radial location relative to the specimen in order to take the necessary measurements. The detector can detect the intensity and/or the wavelength of the diffracted x-rays. All information needed to solve the Bragg equation as well as the Laue equations is available. The x-ray source may be scanned electronically or mechanically. The present invention is used to perform texture analysis and phase identification.

摘要： The present invention provides for a polarization independent optical switch for selectively switching an optical signal from at least one input port to a preselected one of a plurality of different output ports. The optical switch operates to transmit all of the optical signal from an input port to a predetermined one of the output ports without first segmenting the optical signal into two polarizations.

摘要： A liquid crystal light valve is provided which either reflects or transmits all wavelengths of light. Micron size cholesteric liquid crystal micelles are formed by adding a chiral molecule dopant to a nematic liquid and dispersing into a polymeric solution. The chiral dopant twists the micelle into a helical planar order along a helical axis. The interior structure of the micelle is a series of concentric spheres, the distance between the envelopes of which is the pitch. The pitch of the helical planar order of the micelles is adjusted by varying the concentration of chiral molecules which have been added to the nematic liquid. The sense of the helical planar order of the micelles is controlled and the micelles are dispensed in an inert polymeric binder forming a film which may be applied to a surface for controlling the light applied thereto either passing or reflecting the light depending on the temperature of the film. The light valve is controlled in one way by controlling the right and left hand sense of the helical planar order of the micelles by adding equal amounts of chiral dopants which have right and left handed orders.
