The structure of a fiber-optic cylinder pressure sensor for automotive engine is optimized. The fiber-optic sensor utilizes bending power loss in the optical fiber. Because a small local in the fiber affects the sensor characteristics and reliability, it is important for sensor design to have the optimized structure. The sensor output is simulated based on analyses of optical power loss and mechanical deformation of the optical fiber. The simulated results show good agreement with experimental results. Using this simulation method, we optimize the sensor structure so as to obtain both good characteristics and high reliability, taking the effect of dimensional deviation into account. We also find that the allowable deviation of the horizontal dimensions of the sensors is ten times larger than the deviation of vertical dimensions.
