Laboratory Setup for Multiaxial Strain
Strain Measurement
Blue Road has developed a series of sensors capable of measuring single or multi-axis strain as well shear strain and transverse strain gradients with resolutions in the sub-microstrain range. Because multiple sensor gratings can be written onto individual fibers, measurements can be taken at different locations with a single fiber. Strain measurements can even be taken in conjunction with other parameters, such as temperature and pressure.
These sensor systems are ideal for both static and dynamic strain measurements. Static measurements can provide data for constant load applications or for periodic damage checks. Dynamic sensors can offer real-time strain data at rates from 1 Hertz, all the way up to 2 MHz with our fixed filter system. Combined with excellent resistance to electromagnetic interference, light weight, and durability, fiber optic strain sensors have already proven themselves in aerospace, civil, and composites applications.
The following published papers provide examples of some of our previous work on optical strain sensors, in addition to discussion on the principles behind the sensors.
