A dual-function ESPI system is developed for the measurement of out-of-plane displacement and its slope change. The proposed system is convenient and also efficient to switch over from an out-of-plane sensitive configuration to shearography. A differ

Interferometric surface profilers using a single wavelength offer excellent vertical resolution, but have an ambiguity-free range of less than half a wavelength. Multiple-wavelength or white light interference techniques are used to overcome the prob

A real-time phase reversal speckle photography system using BaTiO 3 crystal as a recording medium is developed for phase step calibration. A pi-phase shift on the random speckle pattern is accomplished by varying pressure within an air-filled quartz
