Abstract
A hologram image acquiring apparatus includes a linear polarizer that filters incident light reflected by an object into a polarized component of a specific angle; a spherical lens that partially converts light that is incident through the linear polarizer to a spherical waveform; and a phase shifter that converts a part of the light incident through the spherical lens to a plane waveform having a respective phase per pixel unit.
