Holographic reconstruction apparatus and method

Abstract

Provided are an improved holographic reconstruction apparatus and method. A holographic reconstruction method includes: obtaining an object hologram of a measurement target object; generating a digital reference hologram calculated from the obtained object hologram; extracting each of a first phase information of the object hologram and a second phase information of the calculated digital reference hologram; calculating a phase information difference from the first phase information of the object hologram and the second phase information of the calculated digital reference hologram; and compensating for distorted phase information based on the calculated phase information difference, and calculating quantitative thickness information of the measurement target object by using the compensated distorted phase information to reconstruct 3-dimensional (3D) shape information and quantitative thickness information of the measurement target object.

What is claimed is: 
     
         1 . A holographic reconstruction method comprising:
 obtaining an object hologram of a measurement target object;   generating a digital reference hologram calculated from the obtained object hologram; and   calculating quantitative thickness information of the measurement target object based on a first phase information of the object hologram and a second phase information of the calculated digital reference hologram.
