Laser-based sensing for assessing and monitoring civil infrastructures
T.-Y. Yu, University of Massachusetts Lowell, USA
Abstract:
This chapter provides an overview of current laser-based sensing techniques and their applications in science and engineering. The chapter first introduces the principles of lasers, followed by a technical description of several laser-based sensing techniques including laser interferometry or electronic speckle pattern interferometry (ESPI), digital shearography, scanning photogrammetry, laser Doppler vibrometry (LDV), and laser-ultrasound. Other laser-related techniques are also discussed, with an emphasis on civil infrastructure applications. The chapter then addresses the safety issue associated with the ...
