HOLOGRAPHIC IMAGE RECORDING AND RECONSTRUCTING METHOD

摘要

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.

1. A holographic image recording method, that is realized through utilizing a holographic image fetching and recording device, including a holographic image fetching device, that includes an image fetching device and a rotation table; and a holographic image recording device, that includes: a light emitting unit, a first reflector, a light splitter, a first polarizer, a second reflector, a display panel, a holographic film, a second polarizer, and a third reflector;
the holographic image recording method includes the following steps: using the image fetching device itself remaining fixed, 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 the display panel through a connection line; using a light emitting unit, to emit a coherent light to a first reflector; the first reflector receives the coherent light and reflects it to the light splitter; the light splitter reflects the coherent light along a second light path to the second polarizer, to form into a reference light; the second polarizer polarizes the coherent light into a polarized light, and transmits it to the third reflector; the third reflector reflects the polarized light onto the holographic film along the second light path; the light splitter transmits the coherent light along the first light path to the first polarizer, to form into an object light; the first polarizer polarizes the coherent light into a polarized light, and transmits it to the second reflector; the second reflector reflects the polarized light onto the display panel along the first light path, and then transmits the polarized light through the display panel, with the polarized light carrying the image information on the display panel, to impinge onto the holographic film; and the object light coming from the first light path, and the reference light coming from the second light path interfere with each other on the holographic film, to form a holographic image.
