Laser-Based Ultrasound for Remote and Limited-Access Inspection Applications
Abstract
The design, implementation, and proof-of-concept demonstration of a fiber-based Cassegrain optical scanning system was completed. Optical generation and detection with the fiber-based Cassegrain optical scanning system over 100-m lengths of optical fiber was demonstrated. High peak power, Q-switched Nd:YAG laser pulses (>45 mJ/pulse at 532 nm) through optical fiber in a robust manner was successfully delivered. This program established the absolute thermoelastic generation efficiency for four different laser wavelengths and eight different material/boundary conditions.
