ABSTRACT:
A light conducting rod in which light incident on the surface of the rod is conducted along the rod to its end faces for subsequent detection. The light entering the rod is incident on three neighboring linear arrays of individual mirrors formed along the diametrically opposite surface of the rod; each individual mirror is inclined towards the axis of the rod and cylindrically curved so that the light is reflected back onto the internal surface of the rod at an angle which ensures total internal reflection.
