The rotor (86) is rotated in conjunction with a shaft (84). A pair of reflecting mirrors (88, 90) are secured to the rotor (86) and shaft (84), respectively. Beams emitted from the transmitted beam guiding optical fibers (80) are independently and consecutively led along the same optical path, to a pair of slit members (92, 96) disposed on the side of the rotor opposite the support member (82), while the rotor completes one rotation. Beam passed through the slit members (92, 96) is diffracted by a diffraction grating (98), and diffracted beams are detected by photo-detector array (100).
