Introduction Definition -: Opto-electronic sensors are the solid state devices used to detect
which 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 physical
properties of light sensitive materials. sensors change their electrical features based upon the intensity of light striking
the 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.

CLASSIFICATION OF OPTICAL FIBER SENSORS
• extrinsic sensors. Sensors in which the measurand acts upon light outside
the fiber
• intrinsic sensors. If the light remains guided within the fiber in the measurement
volume
