摘要： A scanning system includes a cable take-up mechanism that uses a series of pulleys that determine the bend diameters of a scanning system. The mechanism is particularly suited for a spectrometric, e.g., infrared, scanning system where moving scanner or sensor head essentially houses only the optical elements while essentially of all the other electronic and optical components associated with the measurement are housed in an easily accessible compartment that is remote from the moving scanner head. Light is transmitted through optical fiber cables. The cable take-up mechanism maintains the fiber optic cable at essentially constant total bend length and bend diameter thereby minimizing any dynamic changes to spectral bend losses as the optical head is scanned. The light weight construction of the sensor head further reduces vibrations associated with the moving scanner head.

摘要： A compact, long lasting sensor for measuring components such as moisture in moving sheets including paper in a papermaking apparatus employs light sources that produce radiation within defined wavelength regions of interest and the light sources are modulated at high frequencies using non-mechanical techniques. A single detector with various radiation sources can measure at all frequencies while keeping information separated. Superluminescent light emitting diode or laser diode light sources can be directly electrically modulates for improved noise rejection. These higher power and bright light sources afford excellent fiber optic launch efficiency and permits the sensor to be scanned at much faster rates over the paper being monitored.

摘要： A spectroscopic sensor for measuring flat sheet product is disclosed. The disclosed sensor uses a combination of spectrometers and single-channel detectors and filters together with a broadband source of illumination to optimally measure multiple properties of a flat sheet product. A spectrometer is used to measure over a spectral range where an easily configurable set of wavelength channels is needed and where the signal-to-noise ratios and spectral resolutions of the channels are consistent with the spectral range and number of pixels of the spectrometer; while one or more single channel detector and filter combinations are used to measure, with high signal-to-noise ratio, at specific wavelengths within or outside the spectral range of the spectrometer(s). Therefore, the single channel detectors can be used to complement the information provided by a spectrometer or to extend the working range of a spectrometer by providing single wavelength measurements anywhere in the visible, near-IR or mid-IR spectral regions.

摘要： Techniques for non-contacting thickness or caliper measurements of moving webs or sheets employ a sensor device that includes a first sensor head and a second sensor head that are spaced apart to define a path through which the moving web travels. The sensor device projects a laser generated, multiple points pattern onto the upper surface of the moving web. Pattern recognition algorithm analysis of the pattern identifies the orientation, e.g., tilt, of the moving web. The device further measures the film tilt, the distance between the first sensor head and the first web surface, the distance between the second sensor head and the second web surface, and the distance between the two sensor heads to provide a highly accurate on-line thickness measurement of the moving web.
