A new type of icing sensor based on optical fiber detection technology is proposed, and the influence of fiber probe structure distribution on the output characteristic curve of the sensor is discussed. Then, the scattering and reflection of light in ice medium are analyzed with the concentric probe structure as the core And optical characteristics of the transmission and design of the corresponding optical signal processing circuit.Experimental results show that the optical fiber icing sensor has better output characteristics under different icing types and the minimum detection limit of ice thickness is 0.2 mm, the maximum detection limit is 3 mm, with high detection sensitivity and large measuring range, demonstrating the feasibility of this new fiber optic detection-based icing sensor.
