aIn most fiber optic gyroscopes instead of counting the pattern shifts as done in RLGs, where the light source is coherent (of one frequency only) the shift in power density is measured since the light source is usually not as coherent as in a RLG. 在多数光纤陀螺仪而不是计数样式转移如做...
aThe MEMS and interferometric fiber-optic (IFOG) technologies are expected to replace many of the current systems using RLGs and mechanical instruments. However, one particular area where the RLG is expected to retain its superiority over the IFOG is in applications requiring extremely high scale-...
In a digital forward receiver, a signal is processed by an optional pre-distortion module after introducing a delay prior to amplifying the decompressed data, and the signal is D2A converted. Output to the unit 340. D2A converter 340 drives the input signal to an amplifier 350 having a ...
The device described in this article is intended to satisfy an industrial need for continuous position sensing over a measurement range varying from centimeters to many meters.As a fiber-optic sensor,it has the well-known advantages of immunity to EMI and an inability to create sparks in a pote...

Another end of each cable flows into a front side recess of the labeling fields to radiate light into a front surface (21) of the light guiding body. The fiber-optic cables are made of polymers.Schrage, Ortwin, Dipl.-Ing.Wieske, Stefan, Dipl.-Ing....
Peer-reviewed work on fiber-optic distributed temperature sensing advanced significantly, moving from innovations in instrumentation, deployment techniques, calibration, and analysis methods to applications. However, exciting advancements in other branches of fiber optics, such as fiber Bragg gratings, ...
The sensor has a segment of a multi-mode light-wave cable whose one of the ends forms a sensor head. The coating and the cladding of a fiber are removed in an area of the head, so that a core (1.7) lies freely and the area is covered with a thin pH-sensitive layer (1.2) of ...
The coating and the cladding of a fiber are removed in an area of the head, so that a core (1.7) lies freely and the area is covered with a thin pH-sensitive layer (1.2) of copolymer that has high refractive index and forms a micro environment for an immobilized coloring material, ...
