Title: High temperature high voltage transducer
Inventor: BERTHOLD JOHN W SR
IPC: G01L7/08
Filed: 1985-02-01
Granted: 1990-08-11
Abstract: A fused silica diaphragm is optically contacted to a fused silica platform. A first pair of transmit and receive optical fibres is positioned in the centre of the gap between the diaphragm and the platform and a second pair of transmit and receive optical fibres is similarly terminated in the gap but is offset from the first pair. A coherent laser source illuminates the bottom surface of the diaphragm via both transmit optical fibres. The light reflected by the bottom surface of the diaphragm causes an interface fringe patern to be created which is intercepted by the receive optical fibres. Through photodetectors and a fringe counting circuit, an interference fringe count is made which, in turn, is utilised to determine the amount of diaphragm deflection.
