All-fiber rotation speed measurement based on dual-beam speckle interference

An all-fiber rotation speed measurement structure based on dual-beam speckle interference is proposed. A distributed feedback laser as the light source generates two independent laser beams through a coupler and two circulators. Scattered by the object, the two laser beams interfere separately with...
