OPTICAL SWITCHING DEVICE

摘要

The invention relates to an optical switching device, comprising an arrangement of at least two optical waveguides extending next to each other, particularly extending parallel to each other, wherein the surfaces of two adjacent optical waveguides (L1, L2) are tightly connected, particularly bonded to each other, such that a multilayer design (OSF) of at least two optical waveguides (L1, L2) is formed, and that two adjacent optical waveguides (L1, L2) of the multilayer design have deviating refraction indices. The invention further relates to a device for the measurement of mechanical deformations and/or displacements, which has a switching device according to one of the preceding claims, the multilayer design (OSF) of which is connected / can be connected by optical waveguides (L1, L2, L3) to at least one element (M, A) that can be mechanically deformed, or locally displaced. The invention also relates to a method for the qualitative and/or quantitative determination of a deformation and/or local displacement of an element, wherein the element (M, A) is connected at least partially to a switching device (OSF) according to any one of the preceding claims 1 to 24, and which is detected by means of a change in a light decoupling, which is the result of the deformation/displacement, from at least one optical waveguide guiding a light, and/or by means of a change of a light coupling in an optical waveguide of the multilayer design.
