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.
