2022年12月9日 · In cardiology, the 4-D hologram technology helps in heart valve replacements, therapy of arrhythmias, and coronary interventions. 4-D hologram technology provides fast growth in healthcare infrastructures and new possibilities in emergency medical care.

2015年10月21日 · In addition to astronomy, the DWLS has found use in creating geometric phase holograms for use in mobile displays, holographic imaging and remote-sensing devices for everything from satellites to cameras.

2022年7月28日 · Results presented in Fig. 4d and Visualization 4 demonstrate the DarkTrack’s ability to analyze dense volumes and track the 4D trajectories of multiple objects recorded via single holographic ...

Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.

4D Digital Holographic Microscopy (4D-DHM) is a new technique capable of performing 3D imaging of moving objects. 3D reconstruction is made from a single hologram, but is restricted to sparse objects that occupy only small part of the volume.

2024年12月5日 · Companies are now developing astonishing 3D visual holograms, pushing the boundaries of what is possible and setting new standards for visual realism and interactivity. Moreover, we will examine the broader implications of holography, particularly in terms of immersive storytelling, data visualization, and user engagement.

2021年3月10日 · MIT researchers have developed a way to produce holograms almost instantly. They say the deep learning-based method is so efficient that it could run on a smartphone. This figure shows the experimental demonstration of 2D and 3D holographic projection.

2021年6月30日 · Now EchoPixel is extending its vision to create the ORs and cath labs of the future with the first software platform that enables physicians to use a digital twin of a patient experienced as a 4D interactive hologram. This Holographic Therapy Guidance (HTG) offers improved imaging that simplifies complex minimally invasive image-guided therapies.

2024年9月24日 · Here, we propose a computer-free, physical diffractive network capable of optically generating holograms (OGH) with extended depth of focus from unknown objects at the speed of light. This OGH diffractive network is composed of passive diffractive layers designed by using self-supervised learning.

6 天之前 · 2.4 Demonstration of Metaholograms in Visible Region. Figure 5 shows photographic images of the fabricated holograms exposed to different wavelengths of light, with Figure 5b,c showing holographic images of the metaholograms calcined at 200 and 600 °C, respectively. The metaholograms calcined at 600 °C clearly exhibited significantly higher ...
