Concise answers to the most frequently asked questions about optical strain gages: procedure, advantages, installation

Optical strain gages are becoming increasingly popular. They are as easy to install as classical SGs, are not electromagnetically susceptible and can also be used in highly explosive atmospheres.

But just how does a fiber Bragg grating work? Are there other advantages? What do I have watch out for during installation? How do I compensate for optical losses? How many sensors can be integrated into a fiber?
