Abstract
An optical fiber (12) extends from a light source (10) along a beam (16) of a sensor (18). The optical fiber terminates in a free end adjacent a free end of the beam and generally opposite to a fixed free end of a target, such as a second optical fiber (20). Light is transmitted across a gap between the first and second optical fibers in accordance with the degree of alignment thereof. The beam (16) has at least two portions (38, 40) extending longitudinally therealong. Each of the beam portions is constructed of a material that changes longitudinal dimension to a different degree than the other in response to the sensed condition. In this manner, the sensed condition causes the beam to bend, altering the degree of alignment between the optical fiber free ends in response to the sensed condition.
