• The relation between the dynamic characteristics of the adjustment element of Bernhardt type autoleveller and the amplitude of the input signal has been studied by the frequency response method<BR>The results are : <BR>(1) The specular component from the total reflection was separated theoretically and some formulars were derived.<BR>(2) The specular component was only 1⁄20 to 1⁄30 of the total reflection for a cotton sliver.<BR>(3) Therefore, the diffused reflection which does not depend upon fiber orientation, should be eliminated for the measurement of fiber orientation.<BR>(4) The specular component on one plane can be derived from that of another plane which is perpendicular to the former and contains the same reflection axis.<BR>(5) The rotating polarizer and the fixed analysers make it possible to measure continuously the fiber orientation of a running sliver.
