Due to its propagation characteristics, spectral composition, and properties of interaction with material (e.g. absorption, reflection, scattering, etc.), light offers a wide variety of possibilities for development of diverse measurement techniques. The basic structure of a sensor system essentially consists of a light engine (light source), the light transmission, the object to be analyzed, the light receiver, and the detection system.
The interaction of the charged light with the object results in a change of the electromagnetic parameters (e.g. absorption, polarization, scattering, fluorescence, etc.), which is measured by the detector system.
In sensor technology, the objects to be investigated are found in various aggregate states (solid, liquid, gas, plasma) and with various container configurations (cuvettes,
vials, planar surfaces, flexible mechanical parts, etc.). Accordingly diverse and different are the associated optical modules for light impingement and detection. |
Advantages of Fiber Optic Sensors
Compared to other sensor technologies, fiber optic sensors exhibit a range of significant advantages, which, depending on the application, constitute a decision criterion. |
