摘要： One embodiment of the present invention provides an optical detection sensor configured so as to irradiate exit light emitted from a light source onto an object to be measured, the object being disposed a relative distance away from an end face of a first optical fiber, and receive the reflection light therefrom with a second and a third optical fiber, thereby computing a displacement amount of the object. In this sensor, the first optical fiber is disposed so that an angle between a longitudinal direction thereof and a normal line to an incident surface of the object becomes θ; the second and the third optical fiber are disposed so as to be mutually parallel and so that an angle between a longitudinal direction of the second and the third optical fiber and the normal line becomes θ; the first optical fiber is disposed symmetrically with the second and the third optical fiber with respect to the normal line; and the first to the third optical fiber have a dNA/dλ of 4×10−5 or less with respect to a wavelength of the light source.
