Abstract
A fiber measurement system for precision measurement of individual fiber properties, including length and fiber length distribution is provided. The fiber measurement system includes a fiber introduction system configured to introduce a plurality of individualized fibers. A fiber guidance enclosure is configured to receive the fibers from the fiber introduction system. The fiber guidance enclosure has an enclosed pathway and a viewing area. The viewing area has a height that limits mobility of the fibers in a Z-direction and the viewing area has a width that is wider than the enclosed pathway. A sensing system is provided for detecting the presence of the fibers within the fiber guidance enclosure. An imaging system is positioned proximal the viewing area of the fiber guidance enclosure to capture an image of the individualized fiber as the fibers pass through the viewing area. A controller is provided for analyzing the image data to determine at least one property of the fibers.
