In a hologram, a three-dimensional image, often referred to as a holographic image, is formed. Unlike conventional two-dimensional images, holograms capture and reproduce the full three-dimensional information of an object or scene. When viewed under proper illumination, a hologram appears to have depth, perspective, and the ability to change as the viewer's perspective shifts.
The holographic fan is created by reconstructing the original object beam that was recorded during the hologram's formation. When coherent light, typically a laser, is directed onto the hologram, it diffracts the light in a way that recombines the scattered waves from the object, recreating the original light field that interacted with the hologram during recording. This reconstructed object beam then interacts with the viewer's eyes, allowing them to perceive the three-dimensional image as if the object were physically present.
It's important to note that the quality and realism of the holographic display image can vary depending on factors such as the complexity of the hologram, the recording and reconstruction techniques used, and the viewing conditions.
