Abstract: Fiber optic sensors employ a high brightness light source such as a fiber optic supercontinuum source, multiplexed superluminescent light emitting diodes, or a broadband tunable laser diode. Light is delivered to the measurement location via fiber optics and sensor optics directs infrared radiation onto material the being monitored that is located in a hostile environment. A disperse element is positioned in the detection beam path in order to separate the wavelengths and to perform spectral analysis. A spectral analysis of the radiation that emerges from the sheet yields information on a plurality of parameters for the material. For papermaking applications, the moisture level, temperature and cellulose content in the paper can be obtained.

Abstract: An in-situ time domain spectroscopy (TDS)-based method (200) for non-contact characterization of properties of a sheet material while being produced by a manufacturing system (700). A time domain spectrometry system (100) and calibration data for the system (100) is provided. The calibration data includes data for transmitted power through or reflected power from the sheet material as a function of a moisture content of the sheet material. At least one pulse of THz or near THz radiation from a transmitter (111) is directed at a sample location on a sheet material sample (130) while being processed by the manufacturing system (700). Transmitted or reflected radiation associated with at least one transmitted or reflected pulse from the sample location is synchronously detected by a detector (110) to obtain the sample data. The sample data, which is coincident data, is processed together with the calibration data (207, 208, 209) to determine at least one, and generally a plurality of properties of the sheet material sample (130) selected from caliper, basis weight and moisture content.

Abstract: An optical, non-contact sensor for measuring the thickness or weight of layered products and particularly those that contain a light-reflective substrate incorporates a reflective surface to cause incident radiation from a light source to plurality of time within the layered products before being detected in a receiver. A diffusing element can be incorporated as a diffuse source of illumination. The Lambertian-type light scattering generated by the diffuse element causes the incident light to interact multiple times with the layered product resulting in enhanced sensor sensitivity to selected components in the layered product and measurement error induced by specular reflection of the light from the reflective substrate is minimized.

Abstract: An apparatus for incorporation into time-domain spectroscopy systems that creates a continuous reference whereby a sample pulses' phase and amplitude can be tracked and corrected employs a beam splitter to generate sample and reference pulses. A detector is positioned for receiving the reference radiation pulses that do not interact with the sample. The same detector is also positioned for receiving the sample radiation pulses that emerge from the sample. The apparatus can be readily implemented by being configured between the emitter and detector of a terahertz time-domain spectrometer. The reference pulse is used to trace the changes in time and amplitude of the sample pulse. Since any changes in the reference pulse will most likely manifest in the sample pulse, the reference pulse is monitored and used to correct the sample pulse and thereby reduce the effects of jitter.

Abstract: A terahertz time-domain spectrometer scanning sensor system includes a transmitter and a receiver that are secured to a mobile scanner head. Optical pump light, in the form of short pulses launched from a stationary laser located remotely from the scanner head, is delivered to the transmitter and receiver through a controlled fiber optic cable arrangement so that variations in temporal pulse relays that are associated fiber optic transmission are minimized. In this fashion, the movement of the fiber optic cable is maneuvered along a defined path so as to control the bends in the cable and thus minimize variations in temporal delays that can otherwise arise as the pulses of light are transmitted through the fiber. Pulses of laser light launched from the laser into the optical fiber will exit the cable with consistent (i) time of arrival, (ii) phase duration, and (iii) polarization state and energy.
