Non-linear joint transform correlator for micro-displacement measurement using speckle patterns

Show other versions (1)

This work presents a procedure for measuring displacements of tens micrometer, in one and two dimensions, based on the correlation between two speckle patterns. For this purpose, two objective speckle patterns arerecorded by a digital camera -one before and one after the object has been moved- and...
