N2 - The influence of the probe-positioning errors on planar near-field holographic phase-less measurement is displayed in this paper. Compared with the traditional near-field measurement, the near-field phase-less measurement diminishes the requirement of the stable and accurate phase. However, probe-positioning errors in phase-less near field measurement will still make the far field calculation results inaccuracy. As for the phase retrieve, different from other techniques, such as iterative Fourier technique (IFT), digital holographic reconstructed technique only needs to measure the amplitude of the near field once, which reduces the measurement time by half. The probe-positioning errors are set through introducing random deviation from the ideal grids along the scanning axes. The simulation results reveal that the near-field holographic phase-less measurement is less sensitive to the normal (z-axis) errors than the traditional near-field measurement.
