Holographic images are created by a small chip-like device called a spatial light modulator. Until now, these modulators could only create images that are either small and clear or large and fuzzy.

For the first time, scientists have created holograms in mid-air that you can actually touch and move with your hands—no ...

The first step in obtaining a conventional holographic image entails splitting the incident coherent laser light source into a reference beam and an object beam (Fig. 1). Whereas the reference ...

Scientists have developed a groundbreaking holographic system that allows users to physically interact with 3D images ...

which uses high-acoustic pressure soundwaves to project a holographic image and remotely print a two-dimensional version of the image in a polymer material like resin. The material is agitated by the ...

the signal amplitude of the hologram decreases as the area of the object in the reconstructed image increases. As the signal amplitude decreases, the image quality of the reconstructed image ...
