Progress in temporal speckle modulation
Time sequential speckle pattern analysis can be very useful for quantitative and quasi absolute shape and deformation analysis of optical and technical surfaces. Speckle methods for measuring deformation can be greatly enhanced with respect to range and resolution by using temporal evaluation of the speckle modulation. It will be shown that vibration analysis can occur with a very simple optical setup.
