Disclosed herein a device acquiring holography and system including the same. The device includes: a beam splitter module splitting a light emitted from an object into a first beam and a second beam which have polarizations in different states; and an optical control module equipped with a first reflective optical element, which is disposed at one side of the beam splitter module and receives and emits the first beam to the beam splitter module, and a second reflective optical element which is placed at the other side of the beam splitter module, receives the second beam and emits the second beam to the beam splitter module so as to have differences of optical path and wavefront from the first beam. The beam splitter module, the first reflective optical element and the second reflective optical element are monolithically installed by being fixed to each other.

An aspect of the present disclosure provides a hybrid recording system, wherein the hybrid recording system, with respect to incident light from a target object, comprises an objective lens, a circular polarizer, a geometric phase lens, a variable waveplate, a linear polarizer, and an image sensor that are sequentially arranged and aligned with one optical axis, and wherein the variable waveplate operates in an ON mode to convert a wavefront of two orthogonal circular polarization components that are output from the geometric phase lens into two orthogonal linear polarization components, or operates in an OFF mode.
