Biax Scanner
Biaxscanner

The laser extensometer - type biax-scanner is used for non-contact measurement of strain or compression of specimen at biaxial load.

Two laser extensometers of the type parallel-scanner are combined to measure strain in X- and Y-direction. The scanning sequence of the two systems is synchronised to each other. A single receiver with special optical components is used for both scanners.
