Abstract

Fiber optic sensors typically suffer from environmental effects that result in drift temperature sensitivity and bending induced inaccuracies. This paper describes a rugged fiber optic pressure sensor free of these inaccuracies and suitable for environmental and process control applications. A high degree of stability and accuracy is achieved through the use of wavelength referencing and in-situ calibration techniques. The critical issues for performance described in the paper are related to the opto-electronic interface the fiber link and the sensing element. Commercialization issues are also addressed.
