A Fiber-Optic Icing Sensor with Multi-Light Paths

Fiber-optic icing sensor is a kind of light-intensitymodulation sensor. It can indirectly measure the ice thickness based on light intensity. To increase measuring scope of the reflective fiber-optic icing sensor, a fiber-optic icing sensor with multi-light paths is presented., a set of fiber array is introduced to measure the transmission intensity of the light for the reflective fiber-optic icing sensor. The Support Vector Machine Regression Algorithm is utilized to fuse the transmission intensity and reflected intensity for estimate the ice thickness. The experimental results show that this proposed method can improve the measurement accuracy and range of the fiber-optic icing sensor. The anti-interference capability of the fiber-optic icing sensor is enhanced simultaneously.
