Laser bond inspection calibration system

A method of determining a calibration result for a laser inspection system comprising a laser bond inspection head configured to apply a laser pulse to a surface of a test structure to identify a strength of the test structure, the method comprising:

• generating a compression wave in a calibration panel responsive to a laser pulse with a beam diameter applied by the laser bond inspection head to an ablative layer secured to a first surface of the calibration panel, the calibration panel comprising the first surface spaced from a second surface by a predetermined thickness, wherein said first surface is generally parallel to said second surface;
• sensing the compression wave using surface motion sensor fixedly spaced from the second surface of the calibration panel by a predetermined distance and positioned on an opposing side of the calibration panel from the laser bond inspection head, wherein a longitudinal axis of the surface motion sensor generally aligns with a longitudinal axis of the laser bond inspection head within a tolerance window defined by the beam diameter;
• and
• outputting a calibration result for the laser inspection system responsive to one or more characteristics of the sensed compression wave.
