Abstract
The paper puts forward a new non-contact icing detection approach. In this approach, an infra-red laser directly radiates on the frozen surface. Because there are great differences between the absorption rate on the ice and the detected surface, the energy reflected using the photoelectric detector was totally different. The received energy is disposed by the signal process circuit, so that the icing information along the chord of the rotor can be achieved. The method is validated by the experiments using the infrared laser with the wavelength of 1450nm, the influence of the flapping and torque movement of the rotor to the signal amplitude is discussed, and the corresponding measures to reduce the influence of the flapping and torque movement of the rotor is put forward to the icing detection system according to the changing rule of the signal amplitude.
