A multipurpose optical sensor including an even number of optical fiber bundles, and optical systems for converting light guided through optical fiber bundles and leaving leading ends of optical fiber bundles into a substantially parallel light beam in a direction at right angles with the axes thereof, and converging substantially parallel light beam incident on axes from a direction at right angles therewith and guiding the thus converged light beam from leading ends into optical fiber bundles in the form of guide light. The optical fiber bundles are concentrically located in the vicinity of leading ends and, one set of optical systems for a pair of opposing optical fiber bundles, with the center of the concentric circle being positioned therebetween, is opposed to each other at an interval and disposed such that substantially parallel light beam leaving one set of optical systems is incident on other set of optical systems, and trailing ends of the even number of optical fiber bundles are constructed such that trailing ends separately receive or give out light.
