• Plastic optical fibre
• Speckle pattern
• Average speckle size
• Correlation processing

A deformation sensing technique with a multimode plastic optical fibre based on intensity speckle patterns correlation coefficient measurement has been presented. Influence of the average speckle size on results of deformation measuring has been studied and discussed. The presented sensing technique provides a good linear response to the applied deformation in a relatively wide operation region. It is shown that the proposed technique is highly sensitive, low-cost and simple to implement in practice.
