Abstract

Accuracy, reliability and cost requirements dictate the need to critically examine fiber optic approaches that are currently being pursued for detecting pressure in medical applications. Typical medical pressure measurements require only moderate sensitivity but high accuracy under environmental conditions. Temperature effects and fiber bending are the most frequently encountered environmental effects limiting achievable accuracy of the intensity encoded pressure sensors. This paper focuses on the effect of the fiber bending in a catheter-type fiber-optic pressure sensor and discusses the dual wavelength technique and additional improvements developed to minimize fiber effects and increase the accuracy and stability of the sensor.
