Abstract: An improved power meter for measuring the energy and wavelength of light emanating from an optical fiber. The meter is an integrating sphere having a source aperture for receiving the tip of an optical fiber and coupling the light from the tip into the sphere's central cavity. The source aperture is modified to include a sterilizable, liquid-fillable insert which mimics the optical environment within tissue. The sphere also has improved baffling and the sensitivity of wavelength verification is improved by means of a rotatable interference filter placed between an exit aperture and a light detector.

Abstract: A light collection device for use in a flame emission detection system such as an on-line, real-time alkali concentration process stream monitor is disclosed which comprises a sphere coated on its interior with a highly diffuse reflective paint which is positioned over a flame emission source, and one or more fiber optic cables which transfer the light generated at the interior of the sphere to a detecting device. The diffuse scattering of the light emitted by the flame uniformly distributes the light in the sphere, and the collection efficiency of the device is greater than that obtainable in the prior art. The device of the present invention thus provides enhanced sensitivity and reduces the noise associated with flame emission detectors, and can achieve substantial improvements in alkali detection levels.

Abstract: A method detects incomplete coverage of hermetic coatings applied to opti fibers during in-line optical fiber fabrication procedures as well as off-line applications. A fluorescent material surrounds the core region of the optical fiber prior to the formation of the hermetic coating on the optical fiber and energy is radiated in the optical fiber to propagate in the cladding mode. This causes an excitation of the fluorescent material to fluoresce in response to the propagated energy. An appropriately disposed detector detects levels of emitted fluorescence along the length of the optical fiber to indicate where the hermetic coating is incomplete or where pinholes in the hermetic coating are located. Optionally, the fluorescent material is located outside of the cladding layer, inside of the cladding layer near its outer surface or throughout the cladding region to fluoresce when excited by the propagated energy. Different wavelengths of radiation can be used which excite different fluorescent materials so that pinholes or incomplete coating coverage can be detected in hermetic coatings that have different chemical compositions.

Abstract: The etendue (throughput or area-solid angle product) of a high resolution interferometer is maintained at a substantially high level by use of a transparent chamber defined by a highly reflective internal surface, the chamber being located at the input to the interferometer. The chamber has an input aperture to admit light into the chamber and an output aperture or exit opening to pass light to the interferometer. By integrating the input light through multiple reflections thereof within the chamber until it exits to the interferometer, the etendue of the latter is substantially enhanced.

Abstract: A rapid and simple opto-electronic measuring method of determining the wavelength and the wavelength-corrected power of monochromatic light sources is indicated. The photodetectors (1, 2) of different spectral overall sensitivity are acted upon through a transfer device by the flow of radiation of the light source to be measured, and the signals (I1, I2) then produced are supplied through a unit (3) for acquisitioning and processing the measurement values to a calculation unit (4). From the signals (I1, I2) a wavelength-specific quantity is derived in the calculation unit which is compared with the wavelength-specific data present in memory unit (6) after one calibration. Thus, the actual wavelength of the light source to be measured can be determined, be indicated by an indicator unit (7), or be supplied through a data interface. When the actual wavelength is known, a wavelengh-specific correction factor can be interrogated in the memory unit, and a wavelength-corrected power can be calculated in the calculation unit. FOr actuation of the photodetectors (1, 2), a radiation splitter, light wave guides with corresponding connection members of Ulbricht balls can be used.
