Area Scanner

The area scanner is used for non contact measurement of strain or compression of specimen at uniaxial load. Thereby the strain can be measured distributed over the specimen area.

Therefore a parallel scanner is extended with a moveable mirror. This allows to displace the scan beam horizontally. So it is possible to measure the strain at up to 250 discrete positions.
