Combined Reduced Phase Dual-Directional Illumination Digital Holography and Speckle Displacements for Shape Measurement
We present a digital holographic method to increase height range measurement with a reduced phase ambiguity using a dual-directional illumination. Small changes in the angle of incident illumination introduce phase differences between the recorded complex fields. We decrease relative phase differenc...
