Abstract
A new in-plane ESPI displacement sensor will be proposed.It is suitable for high frequent 1D displacement measurement with high accuracy. For this measurement an on-line phase calculation is used. This technique is based on a standard phase shift algorithm and leads to the 1D displacement of one object point. Introducing a new simultaneous initialization the decorrelation limit of the present speckle measurement will be exceeded. This will realize a continuous displacement measurement.
