In Reply to Dhiliiban at 02:30 Aug-30-2016 (Opening).

There is a variety of techniques / probes used for the inspection of turbine blades depending on:
In-manufacturing or in-service inspection;
Which defects or other imperfections you're looking for, their dimensions (reject criteria);
Thickness of the material and ROI (region of interest) through the thickness
100% area scanning or certain sections of the part to be checked.

So it's better to specify the inspection task (or scope of tasks) more precisely in order to obtain the needful information in return.
