The fiber itself is used as a transducer in many fiber optic sensing systems (see the section titled “Fiber Sensors,” in ADVANCES IN OPTICAL METROLOGY, the section titled “Optical Fiber Sensors,” in ...
Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...
Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...
Optical or magnetic linear encoders are traditionally used to provide position feedback in applications with frequent product changes or and sophisticated machining. Linear encoders improve the ...
