Abstract
A fastener strain measurement system employs a probe incorporating a laser emitter to provide a laser beam and an acoustic detection device. A system controller is configured to detect an acoustic wave resulting from the ablation created by the laser beam and calculate fastener strain based on the detected acoustic wave.
Claims20
A fastener strain measurement system comprising:
- a probe incorporating
- a laser emitter providing a laser beam and
- an acoustic detection device;
- and
- a system controller configured to detect an acoustic wave resulting from ablation created by the laser beam, said system controller calculating fastener strain based on the detected acoustic wave.
