Research on holographic virtual manufacturing basis

Holography can be used in virtual manufacturing to show real 3D product models. A new method for recording rainbow holograms of a three-dimensional diffused object in one step, is proposed. There is no lens and real slit adopted for recording in this kind of holography, instead, multiple synthetic slits are created by displacing and multi-exposing an object. Thus, it can expand the horizontal and vertical viewable angles of the hologram, and furthermore expand the image depth by controlling the position of the synthetic slit
