Abstract
A method and system for performing two-dimensional laser Doppler vibrometry (LDV) are disclosed. A high speed fiber optic heterodyne imaging vibrometer can be used for the imaging of high speed surface deformation and/or vibration. Images provided by the high speed fiber optic heterodyne imaging vibrometer can be representative of movement, e.g., displacement or vibration, of the surface being imaged.
