Abstract: A holographic image recording method is disclosed, that is realized through utilizing a holographic image fetching and recording device, including the following steps: using an image fetching device to fetch an image of a target object placed on a rotation table rotating at a fixed speed, the image thus obtained is transmitted to a display panel through a connection line; using a light emitting unit to emit coherent light to a first reflector; that reflects the coherent light to light splitter; and the light splitter splits the coherent light along a first light path and a second light path into an object light and a reference light, and transmits them onto a holographic film to interfere with each other, to form a holographic image. A holographic image reconstructing method is also disclosed, to reconstruct and form a 3D holographic image floating above the holographic film.
