Innovative Method of Producing Holograms May Lead To Huge Development in Holographic Display Market
Posted On April 01, 2021
Holograms present a beautiful 3-D version of the world that surrounds us. They are exciting and offer a shifting perspective as per the audience’s position. Moreover, they have the ability to allow the eye to adjust the focal depth so that it can focus on the background and foreground alternatively. For several years, researchers have been keen on making computer-generated holograms. However, the process has always needed a supercomputer so that physics simulations can be churned out. This results in the process becoming time-consuming and yielding less than photo-realistic results.
Researchers from MIT might have found a solution to this problem with the new way of producing holograms. They have developed a method that uses deep learning method to create real-looking holograms and is so efficient that it can be made to run on a laptop quite easily. This development may change the face of the Holographic Display Market forever as this new method consumes less time to produce holograms and may even reach out to the field of Virtual Reality and 3-D printing.
Scientists have always stated that commercially available holographic displays will come around in the coming decade. This new approach, “tensor technology,” is a concrete development towards this elusive statement, and this advancement might lead to holographic displays taking over the general market.
Making and sharing holograms is a challenging task. They encode the brightness and phase of each light wave. This combination helps in depicting the real essence of the scene, complete with its parallax and depth. A hologram, thus, helps in bringing things to life with the help of unique 3-D textures.
To develop the new method, the team used deep learning. This resulted in the acceleration of computer-generated holography, leading to the generation of real-time holograms. They designed a convolutional neural network, a processing technique that uses a chain of trainable tensors that can mimic how humans process visual information.
Tensor holography has the ability to craft holograms in mere seconds with the help of images with depth information. The related information is given by typical computer-generated images and then calculated using a multi-camera setup or LiDAR sensor.
This advancement has led the way to the production of real-time 3-D Holography, which requires less than 1MB of memory. It is an easy to give feature since most smart-phones nowadays have hundreds of gigabytes available. This considerable feat might change people's whole perspective regarding holographic display, and the technology might start getting widely adopted.
