An optical sensor system includes a light emitting unit, a light detecting unit, light radiating optical sensor heads connected through optical fibers to the light emitting unit and light receiving optical sensor heads connected through optical fibers to the light detecting unit, and light is selectively distributed to the light radiating optical sensor heads for radiating light beams from both side surfaces of each sensor head to the adjacent light receiving optical sensor heads for converting the incident light to photo-current; each light radiating optical sensor head has prisms for splitting the light into two beams; however, the stray light is produced at the edge between the reflection surfaces; the stray light is reduced or predictably controlled by forming textured pattern on the side surfaces, a photo-shield member or notches; otherwise, the edge is sharpened by separately forming the prisms.
