A new optical configuration in speckle interferometry for contouring
... interferometric configuration is shown in Fig. 1. The object to be contoured is illuminated normally with a collimated laser beam. The scattered speckle fields are obon either side of the served symmetrically at an angle surface normal via a pair of mirrors ŽM 1 and M 3 . and ŽM 2 and M 4 . placed i ...
