Abstract
The present invention provides a holographic imaging device and a holographic imaging method that have improved performance in which the influence of a refractive index of a cube-type beam coupler constituting an optical system is considered. The holographic imaging devicecomprises the beam couplerconsisting of the cube-type beam splitter arranged between the objectand the image sensorand the calculation reference light hologram generation unitfor generating an inline reference light hologram jrepresenting a light wave on the hologram planeby performing a light wave propagation calculation including propagation inside the beam coupler, on a spherical wave emitted from the condensing point Pof the inline spherical wave reference light L. The inline reference light hologram jis a computer-generated hologram and used for generating an object light hologram g by removing component of the reference light L from a complex-amplitude inline hologram Jrepresenting the object light O and the inline spherical wave reference light L on the hologram plane
