Claim 3:
4. The sensor according to claim 1, wherein:
each reflective surface of rank n is configured to reflect the light wave that it receives in such a way as to form a light cone of rank n+1, the latter extending about a propagation axis of rank n+1;
when n<N, the propagation axis of rank n+1 extends from the surface of rank n to the surface of rank n+1 and through the second focal point of the surface of rank n, the latter being coincident with the first focal point of the surface of rank n+1; and
when n=N, the propagation axis of rank N+1 extends from the surface of rank N to the measuring photodetector;
in such a way that the light wave emitted by the light source undergoes a number of reflections corresponding to the number of reflective surfaces before reaching the measuring photodetector.
