ABSTRACT:
A force-measuring apparatus is provided having a first plate, a second plate disposed above the first plate and spaced apart from the first plate, an optical sensor having at least one optical fiber disposed between the first plate and the second plate, and a clamp for moving the first plate and the second plate together to compress the optical fiber, thereby applying a prestressing force to the fiber to reduce eccentricity effects.
