Embodiment Construction
[0023] The "a method for realizing phase modulation full parallax holographic volume view" of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0024] figure 1 The first embodiment of the method for realizing the holographic volume view provided by the present invention includes a target object (1), a CCD camera (2), a computer (3), a holographic unit (4), a holographic volume view (5), and a laser light source (6), collimation system (7), spatial light modulator (8).
[0025] In this embodiment, the target object (1) is a three-dimensional human figure. The CCD camera (2) is arranged on a plane parallel to the plane of view of the hologram (5). The multi-angle parallax image ( 9). The holographic volume view (5) is spatially divided into multiple two-dimensional functional diffraction holographic units (4), and each holographic unit (4) is a phase-modulated digital hologram, which has the ability to diffrac...
