Abstract
A novel one-shot in-line digital holography based two-dimensional Hilbert demodulation is proposed. By weakening the object wave compared with the reference wave and applying natural logarithmized operation on the in-line digital hologram, the real part of object wave can be well extracted. Then utilizing two-dimensional Hilbert transform to digitally realize π / 2 phase-shift makes it possible to reconstruct the object wave front from single-exposure in-line digital hologram. Preliminary experimental results are presented to demonstrate the proposed method. This technique can be used for real time imaging and monitoring moving objects.
