Embodiment Construction

[0074] The invention will be further described in detail through specific embodiments and in conjunction with the accompanying drawings.

[0075] The following embodiments of the present invention utilize the rich software and hardware resources developed by modern digital image information technology to digitally realize the brilliant ideas of wavefront recording and reproduction in traditional holography in real time. Drawing on the basic principles and implementation methods of digital holographic printing technology, the spatial information to be displayed in three dimensions is sampled with a two-dimensional image array (M*N; at least one of M and N is greater than 2), and the array samples the image information array Projected onto a special functional display screen, the function of the functional display screen is to restore the complex spatial wavefront expressed by the array image sampling, so as to obtain a perfect holographic three-dimensional display for the purpos...

Abstract

A hologram three-dimensional image information collecting device and method, a reproducting device and method are disclosed. The collecting device comprises M*N two-dimensional image picking-up units Cmn to obtain M*N spatial spectrum sample images of an object O being three-dimensional displayed on an arbitrary spatial spectrum S (2); each sample point Smn corresponds to a body pixel Hmn of the object O; the information obtained by each two-dimensional image picking-up units Cmn corresponds to the spatial spectrum image Imn of the body pixel Hmn; thus, M*N sample spatial spectrum images information of the object O in an array is obtained; M*N two-dimensional image picking-up units Cmn are arranged on the spatial spectrum surface S (2) in a predetermined space sample angle Omegamn with their light axis focus on one reference point R in a corresponding space of the object O; each two-dimensional image picking-up unit Cmn focuses on a visual surface of the object O in the corresponding spatial spectrum direction to obtain a clear spatial spectrum image Imn in the direction; wherein, M, N, m and n are natural numbers and at least one of M and N is larger than 2.

Description

technical field [0001] The present invention relates to a photographic collection device for holographic three-dimensional image information. The present invention also relates to a photographic collection method for holographic three-dimensional image information. The present invention also relates to a projection restoration device for holographic three-dimensional image information. The present invention also relates to a A projection restoration method for holographic three-dimensional image information. Background technique [0002] Since the beginning of the last century, scientists have never stopped looking for reasonable ways to solve the problem of "three-dimensional imaging". Although the practical application of three-dimensional cinema and lenticular plate three-dimensional photos in the middle of the last century marked a certain breakthrough, human beings are still far away from the super dream of effectively realizing the intuitive transmission and display of...
