In accordance with the invention, the functions of two TV cameras in the prior art for monitoring polymer coating concentricity and/or carbon coating thickness are accomplished by a single TV camera. Rather than being projected onto an opaque dispersive screen, the forward-scattered mode pattern of each of the orthogonal beams is transmitted through a translucent screen and reflected to an image combining device which transmits both patterns to the single TV camera. The two beams are slightly vertically displaced to establish displaced images of the two patterns. This allows the two patterns to be viewed simultaneously and distinguished by the TV camera. Modified electronics provide for alternate TV scanning of the two images so that a computer can monitor and correct concentricity and/or carbon coating thickness in real time during fiber production.
