Can Holography Change Architectural Space!!!

A thin hologram is one in which the thickness of the recording medium is smaller than the distance between the interference margins that make up holographic images. The thickness of thin holograms can be up to 60nm, using a topological insulation material (SB) 2 / 3 thin film. The developed hologram surface consists of fine random patterns that seem to have no relation to the original scene on the surface.

The refractive index of the volume of the hologram can be modulated in the z-direction by the thickness of the quantity of several periods of the interference pattern to require a thicker hologram with higher diffraction efficiency. The thicker the volume of a hologram or twice as thick as the recording medium, the greater the distance between the interference patterns.

If the angle between the two recording waves is small, the resulting interference pattern has a large period, and only a few periods are recorded along the z-direction by the photosensitive layer. On the other hand, if the interference pattern is small enough, the modulation of the refractive index in the volume of the hologram is 0.02, resulting in low diffraction efficiency.
In digital holography, the holographic surface is treated as a discrete space of k-vector and direction vectors. Hotel-based imaging expresses holographic information as a four-dimensional arrangement of samples in two spatial dimensions (two k-vectors and a directional dimension representing the light field). It records the traditional hologram information (theoretical laws of scanning) in a compact form. As a result, it reduces holographic bandwidth and computing complexity, increases computing efficiency, and reduces the costs of processing holographic information.

Since Hegel’s invention and its associated spatial-spectral discretization, the conventional approach to calculating holographic data has been to simulate optical interference, a physical process for recording optical holograms.

To create holograms from a custom database of more than 4,000 pairs of computer-generated images, the team used scenes with complex and variable shapes, colors, and depth of pixels distributed in the background and the foreground, as well as a new set of physics-based calculations to handle occlusions. Each pair was assigned to an image containing color and depth information for each pixel in its corresponding hologram.

We describe a new holography system that can record holograms at practical 1 mm and 3 wavelengths. These wavelengths can be recorded with excellent sensitivity and resolution using microbolometer arrays, which have improved dramatically in recent years. In just milliseconds, tensor holographs can create hologram images with the depth information of a typical computer-generated image, calculated using a multi-camera device and LIDAR sensors that are now standard in new smartphones.

These properties can be incorporated into the process of creating holograms by artists. In addition, holograms can be used as direct light for commercial applications or as a light for video projection walls and AR displays 6. Laser-visible transmission of holograms can also be used for master recordings, transmissions, reflection transmissions, and holographic prints.
Holograms offer a change of perspective based on the viewer’s position within the hologram, allowing the eye to adjust the depth of field (focus) of the foreground and background. Holograms are only visible when illuminated with light from a certain direction, and walls are no exception.
