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.
