HOLOGRAPHICALLY DISPLAYING LIVE SCENES INCLUDING THREE-DIMENSIONAL OBJECTS

Smart overview of the Invention

The patent application details innovative methods and systems for holographically displaying live scenes with three-dimensional (3D) objects. It introduces techniques for capturing optical holograms of a live scene, processing these holograms digitally, and reconstructing the scene holographically. Additionally, it describes capturing images or videos to compute corresponding holograms, which are then used for the 3D reconstruction of the live scene.

Technical Field

Focusing on 3D object display, this technology enhances traditional two-dimensional (2D) projection and 3D rendering methods. Existing techniques in virtual reality (VR), augmented reality (AR), and mixed reality (MR) aim to replicate holographic experiences through head and eye tracking. Holograms offer a detailed and immersive 3D view, surpassing regular 2D images, making them valuable in fields like medical imaging, manufacturing, and VR.

System Components

The system comprises a holographic capturing system and a display system. The capturing system uses an optical setup to create optical holograms of live scenes with 3D objects. An optical sensor captures sequential holograms, generating data that the display system uses to reconstruct the scene in 3D space. A computing device may be integrated to process this data into digital holograms for display purposes.

Real-Time Processing

In some configurations, the system captures and reconstructs scenes in real time without storing data. The computing device processes sequential hologram data to produce digital holograms, facilitating immediate reconstruction. The display system can handle amplitude-like holograms with phase modulation capabilities, enhancing the realism of the displayed scene.

Advanced Features

The system includes features like a frame grabber to manage data flow between components and techniques for handling mismatches in pixel pitch between sensors and displays. Various interpolation algorithms are employed for scaling digital holograms, ensuring accurate representation on displays. Fourier transform methods are used to adjust hologram data, accommodating differences in sensor and display specifications.
