New electronic methods for applications to hologram interferometry and to the inspection of bonded components are presented. In the present study, the parts inspected are compressor rings and stators with brazed, bonded, or plasma-sprayed abradable seals. It is shown that, with a computer-based filmless system, costly film and fluids and their inherent maintenance are eliminated.
