An arrangement for the detection of icing on the surface of an object includes an optical conductor in which the radiation from a source strikes at least one plane of the conductor, which is located in the area of the surface to be tested and which is accessible from outside the object, and a detector which receive the radiation coming from this conductor plane and converts it into an electrical signal. An evaluation device compares the signal which a threshold value and, depending on the result of the comparison, generates an alarm signal.

An arrangement for the detection of icing on the surface of an object comprising a source for generating a parallel beam of optical radiation, an optical conductor in the shape of a prism and having two faces which project above the surface on which icing is to be detected, said radiation beam striking one of said faces from inside the conductor, a detector which receives radiation reflected from both of said faces and converts it into an electrical signal, an evaluation device which compares the signal with a threshold value and, depending on the result of the comparison, generates an alarm signal.
