Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.
When the incident light hits the core–clad interface at angles larger than its critical angle, the light is completely reflected and guided in the fiber. In
Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity,
These fiber bundles as a whole are enclosed in a thin sleeve for protection. The outer fiber is used to illuminate or focus the light onto the inner parts of the body.
Detection Principles Optical fiber is comprised of a central core with a high refractive index surrounded by cladding with a low refractive index. When light enters the core, repetitive total internal reflection
Strategies for fiber optic sensing can be split into sensitized fiber and intrinsic fiber methods. An example of sensitized fiber is a Fiber Bragg Grating (FBG), used for
3 For diffuse-scan sensors, slanting the sensor to the background decreases the reflection from the background in case of regular reflection material (mirror, mirror-finished stainless steel, etc.)
