Abstract
A laser transmission apparatus utilizing multiple laser beams and beam paths with a diverger lens to provide an illumination pattern that can compensate for lateral movement of the platform during shearography is provided. Further, this optical setup requires no moving parts and does not reduce power of the laser beams as they move through the individual components thereof. From the perspective of the surface being scanned or inspected, the present disclosure may provide two laser images of a single surface that appear to be identical despite the fact that they were taken from two different spatial positions of the moving platform.
