APPARATUS AND METHOD FOR MEASURING THE QUANTITY AND OPTICAL PARAMETERS OF A LIQUID IN A CONTAINER USING THE PRINCIPLE OF OPTICAL LOW COHERENCE REFLECTOMETRY

摘要

An apparatus for measuring the quantity and optical parameters of a liquid inacontainer using the principle of optical low coherence reflectometry isprovided, theapparatus having: a source arm with a low coherence light source; a referencearmincluding a reference lens, a mirror, means for adjusting the distance betweenthereference lens and the mirror and means for measuring the distance between thereference lens and the mirror; a test arm with a test lens; means for dividingthe outputof the source arm between the test arm and the reference arm; means forcombininglight reflected back into the reference arm and the test arm to create aninterferencesignal; and means for detecting and analyzing the interference signal.
