1 December 1991 A microbend pressure sensor for high temperature environments

Commercial multimode optical fibers, coated with aluminum, gold, or polyimide were used in a pressure sensor that squeezed the fiber between a serrated disk and a compliant material. The sensor was tested up to 400F, and was found to perform well only in a uniform temperature environment. Differential thennal expansion within the sensor made the sensor unusable in temperature transients. Preliminary tests show that mode stripping before the photo-detector can improve the transient temperature response.
