An apparatus for measuring the quantity and optical parameters of a liquid in a container using the principle of optical low coherence reflectometry is provided, the apparatus having: a source arm with a low coherence light source; a reference arm including a reference lens, a mirror, means for adjusting the distance between the reference lens and the mirror and means for measuring the distance between the reference lens and the mirror; a test arm with a test lens; means for dividing the output of the source arm between the test arm and the reference arm; means for combining light reflected back into the reference arm and the test arm to create an interference signal; and means for detecting and analyzing the interference signal.

Fiber distribution characteristics such as the bulk average orientation of fibers in composite fibrous materials can be evaluated based on the variation in the speed with which polarized electromagnetic signals propagate through the material as a function of angle. The electromagnetic radiation may comprise terahertz radiation. The composite fibrous materials may be wood-containing materials such as oriented strand board or particle board.
