Abstract
A sensor system for the measurement of the optical conditions at a boundary surface between a first medium that is a solid body and a second medium whose refracting indices are different. The sensor system has an optical unit comprising at least one sending unit with at least one sending element, at least one receiving unit with at least one receiving element, and an optical path connecting the send unit(s) to the receiving unit(s). A light-conducting body with a base surface and two optically active end surfaces is arranged in the optical path, where the base surface of the light-conducting body is attached to the surface side of the first medium between the sending unit(s) and the boundary surface. The first end surface of the light-conducting body is directed towards the sending unit(s) and the second end surface of the light-conducting body is directed towards the receiving unit(s). The two end surfaces of the light-conducting body, the light emission surface of the sending unit(s) and the light admission surface of the receiving unit(s) are made with a predetermined convex shape.
