Popis: | Source wavelength modulation in an unbalanced Michelson shearing interferometer is demonstrated as a means of phase modulation for optoelectronic shearography. This eliminates the requirement for an active phase-shifting component in the detection head. The technique is demonstrated for both static deformation and vibration measurements. |
