Surface contouring of vibrating objects using quadrature transform

Non-contacting measurement of three-dimensional shape or object profile is important in many areas, including medicine, on-line inspection, computer-aided design-manufacturing and reverse engineering. With recent advances in computing technology, some of these techniques have become automated, easier to use in applications and more efficient in data reduction, which has resulted in the development of full-field optical techniques that are being used for real-time profile measurements in a wide range of settings.
