OPTICAL TECHNOLOGIES, INC.

OPTICAL TECHNOLOGIES, INC. (OPTECH) HAS DESIGNED AN INEXPENSIVE FIBER-OPTIC PRESSURE SENSOR CAPABLE OF DETECTING IMPULSES WITH PEAK PRESSURES OF 700 MPA AND A RISE TIME OF 10 TO THE -4TH POWER. THIS FIBER-OPTIC PRESSURE SENSOR PROVIDES THE FOLLOWING MAJOR FEATURES: (1) PRESSURE RANGE > 700 MPA, (2) COST OF SENSOR ELEMENT < $25, (3) DYNAMIC RANGE GREATER THAN 100 DB PROVIDING HIGH RESOLUTION DATA, AND (4) SINGLE OPTICAL FIBER CONSTRUCTION TO MINIMIZE SENSOR SIZE. THE PHASE I TECHNICAL OBJECTIVES ARE: (1) TO DESIGN THE LOW-COST FIBER-OPTIC SENSOR ELEMENT FOR TRANSIENT HIGH-PRESSURE APPLICATION, AND (2) FABRICATE AND TEST THE HIGH-FREQUENCY DEMODULATION ELECTRONICS. THUS, THE PHASE I STUDY WILL VALIDATE THE METHOD INTENDED TO ACHIEVE THE PHASE II GOAL OF CONSTRUCTING INEXPENSIVE TRANSIENT HIGH-PRESSURE FIBER-OPTIC SENSORS, AND WILL PROVIDE THE NECESSARY PHASE II DETAILED SYSTEM DESIGN PARAMETERS.
