Suspension integrated imaging 3D display based on holographic optical elements

The invention provides suspension integrated imaging 3D display based on holographic optical elements. The suspension integrated imaging 3D display comprises two processes of holographic recording and the suspension integrated imaging 3D display of oblique micro-lens array holographic optical elements. In the holographic recording process of the oblique micro-lens array holographic optical elements, signal waves are obliquely incident to micro-lens arrays and converted into oblique spherical waves through convergence of the micro-lens arrays. Interference of the oblique spherical waves and reference waves occurs, and interference fringes are recorded on holographic material so that a holographic plate is obtained. In the process of the suspension integrated imaging 3D display, lighting waves carry micro-image array information and irradiate the holographic plate at the same incident angle with that of the reference waves in recording so as to reconstruct the same oblique spherical waves in recording. The oblique spherical waves carry the micro-image array information and reproduce fully realistic integrated imaging 3D images so that the suspension integrated imaging 3D display can be realized.
