摘要： A method of measuring the surface fiber orientation of paper, rather than the average fiber orientation including its inner layers. Incident light (Li) is emitted from a projector (6) to a paper surface (1a) of paper (1) to be measured at a predetermined angle of incidence ( theta i), and it is reflected at an angle of regular reflection ( theta o) equal to the angle of incidence ( theta i) and received by a photodetector (7). The incident light contains main linear-polarized light having a plane of vibration perpendicular to the plane of incidence and reflection that includes the path of incident light and reflected light. The reflected light (Lo) received by the photodetector contains only the main linear-polarized light. The paper surface (1a) is inclined at a flat angle ( alpha ) with the intersection between the plane of incidence and reflection and the paper surface (1a) being the center axis, and paper (1) is then rotated relatively to the plane incidence and reflection with a line, which passes through the center of the beam incident to the paper surface (1a) and is vertical to the paper surface (1a), as the center axis of rotation. Fiber orientation of the surface of paper (1) is determined from the intensity of reflected light (Lo) received by the receiver (7) and corresponding to the rotating angle of paper (1).

摘要： The present invention provides a non-destructive method capable of real-time or on-line measurement of a wood or pulp fiber without sample pretreatment for the microfibril angle and the path difference, a parameter proportional to the fiber's cell wall thickness. The method employs a circular polariscope in combination with a line spectral camera with the former generating a micrograph insensitive to the orientation of a fiber and determined only by the fiber's properties related to polarized light and the latter capturing a line image cross the fiber and dispersing it into a spectral image to perform a real-time spectral analysis of the fiber's image. The method further uses the spectrum of a background image part contained in the line image that borders the fiber to normalizing the fiber's spectrum. Therewith the method enables measurement of a fiber or a moving fiber oriented arbitrarily for its microfibril angle and phase retardation by acquiring only one image from the fiber and is capable of over-determining the parameters with the light intensity data created at all wavelengths in the spectral range of the equipment used to avoid possible ambiguous results in signal processing. The method of the invention can be modified for real-time or on-line measurement of other birefringent samples including retardation films and waveplates.

摘要： [00129] An image-based measurement technique that directly measures the crepe pattern on a moving sheet employs a suitable arrangement of illumination, optical elements, and an imaging device to obtain digital images of the sheet surface. The image resolution is sufficient to represent tissue crepe folds at the scale of the crepe. A spectral analysis of some or of all the images reveals the crepe folding pitch. Further analysis of the image optionally reveals other crepe structural parameters, such as the distribution of crepe fold orientation angles and distribution of linear fold lengths. Corrective actions can be implemented in response to changes in the crepe structure. The pitch of creping is the primary parameter for describing the crepe pattern; in addition, analyzing the images with a gradient operator can yield information regarding the orientation of the crepe folds and distribution of angles of the crepe furrows on the hood side or equivalently of the crepe seams on the cylinder side.

摘要： An image-based measurement technique that directly measures the orientation of fibers in a moving web that comprises nonwoven material measures the orientation angles of the individual fibers so that a more robust estimate of the statistical distribution of fibers is obtained. The technique includes the steps of: (a) illuminating an area on at least one side of the web with radiation; (b) obtaining at least one digital image of the illuminated area; and (c) calculating the fiber orientation of the web by processing the at least one digital image with a gradient operator thereby analyzing the distribution of observed fiber orientation angles within the image. The gradient operator is preferably of a non-integer order between (1/4) and (3/4) and particularly between (1/3) and (2/3). The use of fractional-gradient operators yields more reliable results than when integer order gradients are employed.
