Abstract: In apparatus for following sun light, at least two pairs of diametrically facing light-receiving elements (30a, 30c and 30b, 30d) are provided along the periphery of a circular end plane of incidence (24) of an optical fiber cable (20) where sun light is condensed by way of a lens 14. The deviation of a condensed light area from the circular end plane of incidence (24) will be effectively detected by the light-receiving elements to control a drive unit (46) which drives an equatorial (18) carrying an optical system including the lens (14) and the end plane of incidence (24) of the optical fiber cable (20). In one embodiment, another light-receiving element (50i) is provided at the center of the end plane of incidence (24) to detect when light condensing area is deviated to a great extent. The output signal of this light-receiving element (50i) is used to perform speed control of the drive unit (46). In another embodiment, a circuit arrangement for detecting abnormal state of the optical system is also used.

Abstract: A mode scrambler capable of converting the mode distribution of light transmitted through an optical fiber into a stationary mode distribution. The mode scrambler comprises a plurality of cylinders arranged in a predetermined arrangement, and a step index optical fiber of 100 .mu.m or above in core diameter and 0.4 or above in numerical aperture wound around and across the plurality of cylinders. The step index optical fiber is wound at least in one 8-shaped wind at least across the two cylinders of the plurality of cylinders. At least the diameter of one of two cylinders across which the step index optical fiber is wound in an 8-shape is not less than ten times and not more than fifty times the core diameter of the step index optical fiber, and the diameter of the other cylinder is not less than that of the former cylinder.
