    • A fiber optic pressure catheter includes a light source, an optical fiber coupled to receive light from the light source and a sensor head that is optically coupled to the optical fiber. The sensor head has a housing defining a chamber coupled to an end of the optical fiber opposite the light source. The housing has an opening which is enclosed by a membrane. The membrane is responsive to pressure differentials between the chamber and outside the sensor head. A resilient ribbon is coupled within the chamber and has a first end fixedly coupled to a support. The ribbon has a second end that is movable in front of the optical fiber. The ribbon is mounted so that the middle portion of the ribbon touches the membrane and is biased by the membrane in response to various pressure differentials. Thus, various amounts of light are reflected back into the optical fiber based on the amount of pressure at the membrane. A detection system is optically coupled to the optical fiber which determines the pressure at the sensor head from the contrast of spectral fringes of light created by an optical coating on the end of the optical fiber and the light reflecting from the ribbon.
    • 光纤压力导管包括光源,耦合以接收来自光源的光的光纤和光学耦合到光纤的传感器头。 传感器头具有限定耦合到与光源相对的光纤的端部的腔室的壳体。 壳体具有由膜包围的开口。 膜对腔室和传感头之间的压差有反应。 弹性带连接在腔室内并且具有固定地联接到支撑件的第一端。 带状物具有可在光纤前方移动的第二端。 色带被安装成使得色带的中间部分接触膜并且响应于各种压力差被膜偏压。 因此,基于膜上的压力量,各种量的光被反射回到光纤中。 检测系统光学耦合到光纤,其根据由光纤端部上的光学涂层产生的光的光谱条纹和从带反射的光线的对比度来确定传感器头部处的压力。
