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
