Low Coherence Off-axis Digital Holography Based on Scanning the Optical Path Difference
A recording method based on scanning the optical path difference was proposed in low coherence off-axis digital holography,due to the coherence length of the light source limit the detected area of the object wave.First,the different areas of detected plane were scaned by changing the optical path difference between the reference wave and the object wave.Then,the phase distribution of each scanning area was obtained by numerical reconstruction for each scanning area of digital hologram.At last,phase stitching technology was applied to stitch each scanning area to achieve the full field of the view of the object wave.
