Speckled output
WebAn intruder alarm for protecting the perimeter of an area utilizes a multimode optic fiber as the deformable sensing element, wherein a length of multimode optic fiber is buried in the ground of an area or perimeter to be protected. As coherent light from a laser is directed through a length of optic fiber, the output light pattern therefrom is speckled. WebDec 1, 2024 · Fig. 4 shows the output field for an initial beam with a radius of 15 μm, and a power of 10 W for the considered model. The beam at the fiber output is distorted, but it …
