Thermal Diffusivity Measurements of Metals and Alloys by Making Use of the Phase Shift of Laser-Induced Thermoelastic Wave
Thermal diffusivity measurement Thermo elastic wave CO2 laser
2009/6/8
This paper describes a method of obtaining the thermal diffusivity of a metal sample of known thickness. By irradiating an intensity-modulated laser beam of 8 W to the sample at power density of 1.5 ×...
Fiber-optic sensor to estimate surface roughness of corroded metals
fiber optic sensor scattering principle
2011/5/6
A fiber optic sensor system is developed to probe the surface texture of corroded metals. The present work is based on the principle of scattering of light by objects. A light beam from an LED source ...
