Abstract: Disclosed is an apparatus for identifying authenticity of a holographic image, which is capable of identifying the authenticity by comparing a holographic image reconstructed by irradiating light having the same characteristic as an irradiation characteristic of a first reference beam used in generating the holographic image with an original image. Accordingly, since an image or a pattern is recorded by using a reference beam having a specific angle and a specific laser wavelength band in making a hologram, replication or copying for forgery is prevented from being easy.
