Introduction Definition -:

Opto-electronic sensors are the solid state devices used to detectwhich effect light beams either interrupting the beam or reflecting

the beam back to its source.Principle of Operation-:

Opto-electronic sensors make use of the physicalproperties of light sensitive materials. sensors change their

electrical features based upon the intensity of light strikingthe receiver.

FEATURES OF OPTICAL

FIBER SENSOR

Optical fiber can also be used in applications

such as sensing and measurement besides

communication.

Fibers have been incorporated into optical

systems to detect or measure a wide range of

quantities including temperature, pressure,

acoustic signals, vibration, rotation, strain,electric current, magnetic fields, fluid flow rate,

gas concentration and even X-ray.

CONCLUSION

Opto-Sensors are quite simple for most

applications, and not only communicate

with programmable controls, but canincrease product quality and manufacturing

speed, as well as reduce size and costs.

Thus opto-sensors are going to play agrowing and critical role in the modernized

industry.
