Abstract: A scanning apparatus for scanning a hologram is capable of filtering off a holographic picture in the hologram. The hologram includes an image layer having an image to be scanned and a laser layer having the holographic picture. The laser layer has a maximum penetrable incidence. Light with an incidence larger than the maximum penetrable incidence fails to pass through due to light reflection so as to prohibit the image light of the image layer from light transmission. The scanning apparatus includes a load platform and a chassis. The load platform is used for placing the hologram thereon. Besides, the chassis includes a light source for emitting a light. When the scanning apparatus performs scanning, light penetrates the image layer to reflect the image to be scanned and further penetrates the laser layer. After a signal processing procedure, a scanned image is obtained without being influenced by the holographic picture.
