摘要： A holographic light shaping diffuser (LSD) is formed from a monolithic glass material by recording light shaping structures (sometimes collectively known as “speckle”, particularly when the structures extend into the interior of the diffuser) in the glass material during its formation. A volume LSD may be produced by the photolithographic writing or other imaging of light shaping structures in a photosensitive glass material. Alternatively, a surface LSD may be produced by this imaging process or by embossing light shaping structures onto a high quality optical glass or by embossing a light shaping structures on a glass film layer coated onto a substrate. Both types of diffusers control the angular spread of transmitted light while homogenizing otherwise spatially noisy light sources such as LCDs and filamented light sources and while maintaining damage thresholds consistent with any glass optical element. The LSD has a transmission efficiency of over 90% from the Ultraviolet wavelengths through the physical spectrum and into the near-infrared. Moreover, because the LSD is a true glass, it is capable of withstanding temperatures well beyond glass transition temperatures of plastic LSDs, can be formed in a convex or concave surfaces through conventional molding, grinding, or polishing techniques, and can be coated by hot-coating techniques. The LSD also has a very high laser power threshold.

摘要： A photosensitive sol-gel film containing an organometallic photosensitizer is deposited on the oxide containing surface layer of a silicon substrate. A pattern of white or ultra violet light incident to the photosensitive sol-gel film results in the unbinding of the photosensitizer from the exposed regions of the sol-gel film. A subsequent succession of first and second heating steps results in, first, the removal of the photo sensitizer constituents from the exposed regions of the sol-gel film and, second, the removal of the organic constituents from the exposed regions, resulting in regions doped with a metal oxide with non linear optical properties, such as semicondutive, etc. properties. Optical switches, couplers, waveguides, splitters, interferometers wavelength division multiplexer, Bragg gratings and more can be fabricated. A glass substrate also may be employed, instead of a silicon, in which case a separate silicon oxide surface layer is unnecessary.

摘要： A low cost portable fiber optic fluorometer is packaged as a personal computer peripheral and is based on interchangeable modules. One embodiment of the fluorometer comprises an excitation source, a detector, a signal processor, frequency source, wavelength selector, and an optical interface. The optical interface is exclusively fiber optic-based, thereby simplifying optical alignment and reducing the cost of the fluorometer. In another embodiment, the excitation source is an inexpensive monochromatic excitation source. In this case, the monochromatic excitation source and the first wavelength selector are preferably removable and replaceable, so that the fluorometer is advantageously able to generate different excitation wavelengths and detect different emission wavelengths. A fluorescence measurement method comprises the steps of generating an excitation signal; transmitting the excitation signal to a system under study which, in response, generates an emission signal; and detecting both the excitation signal and the emission signal with the fluorometer, and then using the detected excitation signal as a reference signal to calibrate the fluorometer and to nullify distortion errors in the emission signal. The use of the excitation signal as a reference signal provides an advantageously simple way to calibrate the fluorometer and to nullify distortion errors in the emission signal. An alternative method allows the precise shapes of the emission signal and the excitation signal to be profiled. The fluorometry method and apparatus can both advantageously be used for performing both direct fluorescence lifetime measurements and for performing phase fluorometry.

摘要： A method of determining the wavelength of light transmitted in an optical fiber comprises the steps of filtering the light using a filter, and then detecting the filtered light, and then determining the wavelength of the filtered light. The filter comprises a fiber grating which is recorded in a portion of the optical fiber. The fiber grating preferably has a modulated index of refraction with a modulation amplitude that varies from a first end to a second end of the fiber grating, and a modulation period defined by a grating constant that varies from the first end to the second end of the fiber grating. The fiber grating at least partially prevents transmission of light within a wavelength spectrum, and prevents transmission of a substantially larger portion of the light at a first end of the wavelength spectrum than at a second end of the wavelength spectrum. Therefore, the wavelength of the filtered light can be determined by determining a proportion of the light which was transmitted by the filter. The proportion of light which is transmitted by the filter is preferably linearly related to the wavelength of the light.

摘要： A fiber optic sensor for sensing the presence of an analyte has a plurality of optical fibers each of which has at least one analyte sensing segment and one or more low loss lead portion, where the optical fibers are disposed on the periphery of a fiber carrier. The analyte sensing segments may be disposed in an offset relationship to provide continuous detection over a desired distance or they may be spaced apart to provide detection at selected locations. More than one set of optical fibers with sensing segments may be combined to provide detection of multiple analytes. Multiple fiber carriers allow each segment or the grouped sets of segments to be coupled together over a distance either in offset relationship or in spaced apart relationship.
