Abstract :
A novel intensity modulated fiber optic accelerometer employing a graded-index (GRIN) rod lens is described, the paper presents the operational principle of this device. According to the theoretical analysis, we show how to select the parameters of the GRIN rod lens, fibers and other elements in the design. Due to the novel structure, the displacement sensitivity of this sensor is a factor of 2 better than the conventional lateral displacement sensor
