Abstract:
In a method for measuring a fiber-like particle (100, 210) in a suspension flowing in a substantially equilateral cross-section capillary tube (200), the improvements in that:for measuring a length and transverse measure of the fiber-like particle (100, 210), a position of the fiber-like particle (100, 210) is determined and a real image is formed of the fiber-like particle (100, 210) in the equilateral cross-section capillary tube (200) one or more times from at least one direction; anda measurement point along the fiber-like particle (100, 210) of the transverse measure of the fiber-like particle (100, 210) is adaptively controlled from the length measurement of the fiber-like particle (100, 210).
