Document Type and Number:
WIPO Patent Application WO/2019/078384
Kind Code:
A1
Abstract:
Disclosed are an improved holographic restoration device and method. The holographic restoration method of the present invention comprises the steps of: a) acquiring an object hologram of an object to be measured; b) generating a digital reference hologram calculated from the acquired object hologram; c) respectively extracting phase information of the object hologram and phase information of the calculated digital reference hologram; d) calculating a phase information difference from first phase information of the extracted object hologram and second phase information of the extracted calculated digital reference hologram; and e) compensating for distorted phase information from the calculated phase information difference, and calculating quantitative thickness information of the object to be measured by using the compensated phase information, thereby restoring three-dimensional shape information and quantitative thickness information of the object to be measured.
