Abstract
Many of Japan's social infrastructure facilities are now entering the latter half of their lifetime. In such circumstances, time- and cost-effective in-situ inspection for SCC (Surface Corrosion Cracking) is required urgently even in the power generation plant market. Optical full-field inspection using pulsed electric speckle pattern interferometry (ESPI) realizes time-effective flaw-screening inspection and will be suitable for RBM (Risk Based Maintenance). Full-field inspection using pulsed ESPI was experimentally demonstrated and simulation results using finite difference method determined attractive performance points.
