Fundamentally, the Lytro is a device that exaggerates the effect of light
arriving at its sensor from oblique angles. Used in conjunction with a laser
light source, it might aid in detecting flexing, and therefore potential
failure, in metal structures like airplanes, storage tanks, etc. It's just a
thought. I'm not a structural engineer and know almost nothing about the
subject.

The data ought to be able to provide 3D imaging. With macro focus
stacking software, you can generate 3D stereo pairs or 'rocking'
animations where the subject tilts a little back & forth.
