..., such as sound waves. The two methods currently available for practical nondestructive inspection are optical holography, using visible light waves, and acoustical holography, using ultrasonic waves. Optical Holography Optical holographic interferometry has been successfully used both in research...

... Calculation Residual strains for weld HAZs are often measured by strain gages ( Ref 35 ). Nonobtrusive techniques such as interferometry are also employed by some researchers ( Ref 59 , 60 ). For postweld residual strain measurements, x-ray diffraction is the most popular. Recently, neutron scattering...
