Abstract

In this proposal, AlphaSense, Inc. details the development of a fully integrated laser ultrasound visualization and laser ablation tool for corrosion identification, removal and cleaning. The key innovations of this proposal include the following: a) Hidden corrosion detections based on direct visualizations of the ultrasound propagation characteristics, b) Corrosion product removal using laser ablation, and c) The implementation of a fully integrated corrosion detection and removal tool. With such innovations, the merits of the proposed corrosion detection and removal tool include the following: a) Fully integrated, compact and portable, b) Capable of detecting hidden corrosions, c) Compatible with complex shapes, configurations and tight space constraints, d) High sensitivity and good spatial resolution, e) High throughput in both corrosion detection and removal, f) Controllable and no collateral damages, and g) Easy and safe to the operators.
