How to truthfully render the huge amount of data to viewers by a real-time, high-resolution, 3D display is a severe challenge for display technologies. Holographic display has potential to provide all depth cues that human eyes can perceive because it addresses the wavefront of 3D objects.

Hololab develops high-efficiency computer  generated holographic algorithms the devices  such as phase-SLM,  DMD or metasurfaces.

Holographic Display

Computational imaging can improve the capabilities of a camera, and reduce the cost and size of camera elements. Modulators are employed to break the limit of the resolution of the traditional system. Digital holography is a typical lensless computational imaging method. Numerical focusing  could  support the 3D reconstruction from a 2D hologram captured  by a imaging sensor.

Hololab develops high-resolution  and  low-noise digital holographic algorithms  and systems based on phase retrieval,  compressive sensing and deep learning technologies.

Holographic Imaging

Volume holographic provides high-density, large-capacity, high-speed data storage due to its angular and wavelength selectivity. The data could be stored page by page rather than bit by bit as 3D volume holograms in the photorefractive crystal or photopolymer.

Hololab has developed various holographic optical storage technologies and systems, from speckle multiplexing technology to 3D encoding algorithms.

Holographic Memory

Multichannel volume holographic optical correlator has the characteristics of high-speed, high parallelism and multichannel processing. It may have the potential applications in the area requiring high speed, real-time, high-capacity correlation calculations, such as associative retrieval, pattern recognition, target tracking, navigation, and so on.

Hololab has developed an integrated holographic optical processing unit for human facial recognition, fingerprint identification and remote images processing.

Holographic Computer
Holographic Communication

The 5G network has the advantage of ultra-high transmission bandwidth, which will accelerate the developments of new three-dimensional communication systems. Computer-generated holographic display is an ideal solution for 3D communication because it could provide realistic 3D effect.

Hololab is now developing a holographic communication system based on light field camera, 5G network and holographic display system.

Holographic Optical Element

Volume holographic grating could be used as irreplaceable filters for spectrometer, laser, and waveguide, due to its high diffraction efficiency, Bragg selectivity and low cost.

Hololab has developed volume holographic optical elements based on homemade gold nanoparticles doped PQ/PMMA photopolymer.
