Abstract:
An optical sensor and an abnormality detection method therefor are provided. The optical sensor includes a light source device that generates light to be irradiated to an object; a light receiving part that receives a reflected light from the object; a branch part that fuses a first optical fiber optically coupled to the light source device and a second optical fiber optically coupled to the light receiving part to join with one end of a third optical fiber facing the object; and a processing part that determines whether junction abnormality occurs at a junction between the third optical fiber and the branch part based on whether an increment in a received light amount detected by the light receiving part with respect to a reference detection amount which is detected in a state of no reflection from the other end of the third optical fiber is within a predetermined range.

Claim (Index 1):
An optical sensor for measuring a distance to an object or a displacement of the object based on a reflected light from the object, the optical sensor comprising:\n a light source device that generates light to be irradiated to the object; a light receiving part that receives the reflected light from the object; a branch part that fuses a first optical fiber optically coupled to the light source device and a second optical fiber optically coupled to the light receiving part to join with one end of a third optical fiber which faces the object; and a processing part that determines whether junction abnormality occurs at a junction between the third optical fiber and the branch part based on whether an increment in a received light amount detected by the light receiving part with respect to a reference detection amount is within a predetermined range, wherein a received light amount detected by the light receiving part in a state of no reflection from the other end of the third optical fiber is set as the reference detection amount.
