Method and system for adjusting the sensitivity of optical sensors

A method and a system for adjusting the sensitivity of an optical sensor are provided. A first beam of light in an optical fiber is separated into first and second portions propagating therethrough at a first speed. A second beam of light is directed into the optical fiber to interact with the first...

Zusammenfassung:A method and a system for adjusting the sensitivity of an optical sensor are provided. A first beam of light in an optical fiber is separated into first and second portions propagating therethrough at a first speed. A second beam of light is directed into the optical fiber to interact with the first beam of light such that the first and second portions propagate through the optical fiber at a second speed. The propagation speed in turn influences the sensitivity of the optical sensor.
