Whenever electrical signals are not advisable (eg measuring the flow of highly-volitile liquids), optical sensing can offer a cheap, reliable alternative.

Optical sensors can measure a range of parameters such as distance, optical density, turbidity of fluids, and rotation without relying on mechanical parts and hence improve reliability.

"The above image shows a prototype low-cost optical rotation sensor assembly. This type of sensor over comes the need for mechanical bearing and slip-rings to accurately measure angular position"
