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
