OUR SEA : International Journal of Maritime Science & Technology, Vol.56 No.1-2 June 2009. -

This article presents a brief overview of fiber-optic sensors and their development in the past 30 years. The new

technologies like FBG or OTDR sensing principles have formed an entirely new generation of sensors. Some of these

sensors, depending on their applications and measurands, have been successfully commercialized and they are

shown in this article.

Also, a multimode fiber optical sensor that measures vibrations, is presented. Multimode fiber has a relatively large

number of modes that travel simultaneously through the fiber and interfere with each other. By applying various

forces upon the fiber, mode’s way of propagation will be changed, consequently their interference distribution will

be changed, therefore generating a different field pattern at the fiber end. Difference in field pattern can be used for

obtaining vibration parameters such as the amplitude and the frequency.
