    摘要: The inner eye of a surgical patient is illuminated by incorporating an optical fiber in a ring configuration imbedded into or attached to a contact lens. The viewing surface of the lens if planar to optimize the surgeon's view. The opposite surface of the lens is curved to conform to the patient's eye. A solution conduit irrigates the eye. The apparatus is easily positioned and easily directed. The apparatus also is sufficiently inexpensive to be disposable.

    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 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 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 method and apparatus for processing an optical signal in an optical waveguide using a closed loop wavelength dependent active tuning system. A tunable fiber Bragg grating, optical processor and a controller provide feedback control of the central wavelength of the tunable fiber Bragg grating. Changes in wavelength of the processed signal are followed to keep the tunable fiber Bragg grating tuned to a peak wavelength for maximum sensitivity.
