Abstract
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.
