OPTICAL SENSOR SYSTEM
[attachment=25515]
WHY WAS OPTICAL SENSOR SYSTEM INTRODUCED?
FOR OXYGEN AND PH MEASUREMENT FOR OCEAN OPTICS.
IT LESSENS THE RELIANCE ON THE ELECTROCHEMICAL TECHNOLOGIES THAT HAVE DOMINATED THE FIELD OF OXYGEN SENSING.
OPTICAL DISTANCE SENSOR
ELECTRONIC DEVICES USED TO SENSE THE PRESENCE OR ABSENCE OF AN OBJECT .
THESE ARE PHOTOELECTRIC SENSORS OR PHOTO EYES USED IN CARS TO DETECT THE DISTANCE FROM AN OBJECT.
OPTICAL FIBER SENSOR
OPTICAL FIBERS ARE MINUSCULE WIRES MADE OF WIRES OR PLASTIC THAT ARE CAPABLE OF TRANSMITTING MASSIVE AMOUNTS OF INFORMATION THROUGH PULSATION OF LIGHT.
THEY CARRY BINARY OR DIGITAL DATA IN COMPUTERS AND TELECOMMUNICATION NETWORKS.
PHOTODETECTOR
LIGHT-SENSITIVE SEMICONDUCTOR MATERIAL.
RANGE FROM PHOTOCELLS TO PHOTODIODES.
THE DETECTOR IS A PART OF SWITCHING OR AMPLIFICATION CIRCUIT.
PYROMETER
ESTIMATES THE TEMPERATURE OF AN OBJECT BY SENSING THE COLOR OF LIGHT IT
GIVES OFF.
ARE USED WHEN DIRECT CONTACT IS INCONVENIENT,UNSAFE OR IMPOSSIBLE.
