Holography is a unique technology that can be used to record three-dimensional (3D) information on two-dimensional media, such as a photographic film. Although holograms comprise analog data, 3D image processing, measurement, and optical signal processing can be realized by combining them with computers. This enables the application of this technology in a variety of fields, ranging from 3D television to microscopes and extremely fast image processing.
However, the realization of such a system requires considerable amounts of light wave computation, and the development of high-speed algorithms and computational hardware is essential for its practical application. In collaboration with researchers in Japan and abroad, we intend to conduct the following research on holographic image processing and information processing.
- Development of high-speed algorithms and computational hardware
- Development of holographic projectors and 3D display systems
- Development of holographic AI information processing
Item 1 is the most fundamental component of this research. We aim to achieve overwhelmingly high speed in holographic computation from both algorithmic and hardware-related perspectives. Once developed, this technology will enable holography-based video games and 3D microscopes, whose realization has been challenging in the past. In addition, the fundamental technology developed in this research will be widely available to users from an open-source library.
Item 2 realizes a holographic display system (holographic projector and 3D display system) based on ultra-fast holographic computation technology. Once developed, it will enable the faithful reproduction of light wavefronts using holography, allowing it to present three-dimensional images that resemble real objects. In combination with "volume display technology," this research will advance the technology development for human-sized image presentation.
Currently, semiconductor-based AI is at the height of its popularity. However, several problems continue to plague it, such as limited performance due to limitations on the speed of electrical signals in semiconductors or high power consumption. We address these issues in Item 3?we intend to develop optical AI using the optical control properties of holography. This technology will enable AI processing at the ‘speed of light’ and reduce power consumption. Conversely, we also intend to attempt to realize greater memory-saving and high-speed AI using a novel semiconductor-based AI technology incorporating the 3D information recording characteristics of holography into semiconductor-based
