- 10 - FUSED SILICA DIAPHRAGM MODULE FOR HIGH TEMPERATURE PRESSURE TRANSDUCERS ABSTRACT OF THE DISCLOSURE A high temperature pressure transducer and sensing apparatus to determine the deflection of the transducer diaphragm is disclosed. The pressure transducer utilizes a fused silica diaphragm (12) which is illuminated at selected locations by a coherent laser source (52) via opti- cal fibers (38, 46). The light reflected by the diaphragm (12) forms interference fringe patterns which are focused by gradient index rod lenses (36) on the ends of optical fibers (40, 48) for transmission to a fringe counting cir- cuit (54). By digital techniques, the fringe count is converted into a determination of diaphragm deflection.
