Abstract
THE PROPOSED NON-INTRUSIVE SENSOR IS AN OPTICAL ANALOG OF A RADAR ALTIMETER. THE CARRIED IS AN INFRARED BEAM GENERATED BY A LASER DIODE, WHICH IS MODULATED BY A MICROWAVE SIGNAL. A COMPARISON BETWEEN THE PHASE OF THE RF MODULATING SIGNAL AND THAT OF THE DETECTED OPTICAL SIGNAL PROVIDES THE DISTANCE MEASUREMENT. OPERATION IN THE INFRAREDMINIMIZES THE EFFECTS OF PARTICULATES ON OPTICAL PROPAGATION, AND THE MINOR EFFECT OF GASES ON THE REFRACTIVE INDEX MINIMIZES ERRORS FROM TEMPERATURE AND PRESSURE FLUCTUATIONS.
