Abstract
A hologram acquisition apparatus and a hologram acquisition system are disclosed. A hologram acquisition apparatus includes a beam splitter configured to split light emitted from an object into a first beam and a second beam, a first reflective optical element configured to receive and emit the first beam to the beam splitter, and a second reflective optical element configured to receive and emit the second beam to the beam splitter and formed as an annular spherical array having discontinuous surfaces, wherein the second reflective optical element has a plurality of segment regions that are concentric and divided to have the discontinuous surfaces and, the plurality of segment regions are formed to have the same focal point.
