Claim 0:
1. A 3D holographic imaging apparatus comprising:
a fluorescent unit configured to cause a plurality of qubits composing a 3D qubit model to emit a plurality of qubit fluorescent beams by applying an imaging beam;
a lens unit comprising configured to change the plurality of qubit fluorescent beams to a desired route;
a light modulator configured to modulate each phase of the plurality of qubit fluorescent beams for each predetermined position, and control a position of a focal point; and
an imaging unit configured to image the plurality of qubit fluorescent beams modulated by the light modulator in a 2D image,
wherein the lens unit comprises a first lens having a focal distance of f1 and configured to change routes of the plurality of qubit fluorescent beams emitted by the 3D qubit model and a second lens having a focal distance of f2 and configured to refract the plurality of qubit fluorescent beams passing through the light modulator to become a predetermined position of the focal point,
wherein a primary image plane (PIP) vertical to an advancing direction of the plurality of qubit fluorescent beams is disposed at 2L, where L is f1+f2, and
wherein the light modulator is disposed on quasi-image plane (QIP), which is parallel to the PIP and spaced apart from the PIP at a predetermined distance of d to an opposite direction of the advancing direction of the plurality of qubit fluorescent beams.
