A method and apparatus for measuring the length of fibers is provided. The method includes the steps of separating the fibers in order to obtain a fiber in single form. The method further involves passing the fiber by an optical measurement system that optically images the fiber. Another step includes calculating the length of the fiber by measuring an increment of the fiber in the x coordinate plane, the y coordinate plane, and the z coordinate plane. Also, the method involves repeating this step to obtain additional increment measurements. These measurements are placed into an equation to compute the length of the fiber. The apparatus for measuring the length of separated fibers from a fiber band includes an apparatus for separating the fiber from the fiber band. Further, a duct is provided for transporting the fiber. At least one camera is proximate to the duct for obtaining an image of the fiber, and a computer is connected to the camera. The computer is configured to assign numerical values to image points of the image of the fiber in the x, y, and z directions. The computer uses the image points to incrementalize the image of the fiber. Also, the computer measures each increment and places the increments into an equation to determine the length of the fiber.
