Abstract
An apparatus for measuring deformation of a body includes a transmitting optical fiber for connection to a light source and having a light exit face for radiating light, and at least first and second receiving optical fibers which have their light entrance faces adjacent to each other and which can each be connected to a respective input of an evaluation unit. The optical fibers are so arranged that upon deformation of the body there is a change in the difference between the amounts of light impinging on the light entrance faces of the receiving optical fibers.
