PHASE SHIFTER FOR DIGITAL HOLOGRAPHIC SYSTEM DIGITAL HOLOGRAPHIC SYSTEM COMPRISING THE SAME AND METHOD FOR MANUFACTIRING THE SAME

摘要

The present invention relates to a phase modulator for a digital holography system, and more particularly, to a phase modulator for a digital holography system, in which a three-dimensional image of a measurement object is acquired in real time using a refractive index pattern (RIP) And includes a first medium 152 and a second medium 154 coupled with the first medium 152, and the first medium 152, the first medium 152, And the second medium 154 are smaller than the difference between the refractive indexes of the first medium 152 and the air or the refractive indexes of the second medium 154 and air.
