Components of Opto-Electronics:
Semi conductor materials:
Elemental semiconductors-Silicon, Germanium
Binary semiconductors-Aluminium, gallium, indium, phosphorus, arsenic, antimony
Ternary semiconductors-Aluminum, Gallium, Arsenic
Quaternary Semiconductors-Indium, Gallium, Phosphorous, Arsenic
Why Opto-electronics sensor system used:
-
The sensors used in an automotive environment must be reliable
-
Produce exactingly accurate results
-
Require little maintenance
-
Help reduce overall system cost and extend the life of the system or sub system unit
-
Integrated optoelectronic sensors are non-contact sensors, that is, they are able to perform their sensing or measurement functions without the need for physical contact with other parts of the system or sub-system
Advantages:
-
Reducing the number of required components
-
Improving the reliability of the system or sub-system
-
Improving the styling, aesthetics and ergonomics of the overall vehicle through better utilization of the available space
-
Improving the manufacturability of the vehicle by reducing the number of sensors that need to be positioned during production
Disadvantages:
-
They are not giving any direct feedback
