HOLOGRAPHICALLY DISPLAYING LIVE SCENES INCLUDING THREE-DIMENSIONAL OBJECTS

Smart overview of the Invention

The patent application describes methods and systems for holographically displaying live scenes with three-dimensional (3D) objects. It involves capturing optical holograms of a live scene, processing these holograms digitally, and then reconstructing the scene holographically. Alternatively, it can capture images or videos and compute corresponding holograms for the same purpose. This technology aims to enhance the realism and immersion of 3D displays beyond traditional 2D and hybrid 3D techniques.

System Components

The proposed system includes a holographic capturing system and a holographic display system. The capturing system utilizes an optical setup to generate and capture optical holograms of live scenes, producing sequential hologram data. This data is used by the display system to reconstruct the scene in 3D space. A computing device may be incorporated to process the hologram data into digital forms suitable for display.

Real-Time Processing

Some implementations allow for real-time capturing and reconstruction of live scenes without storing the sequential hologram data. This involves processing the data immediately to generate digital holograms, enhancing efficiency and immediacy in applications requiring live interactions or displays.

Data Handling and Display

The system can include a frame grabber to manage which parts of the hologram data are processed and displayed. The computing device plays a crucial role in adapting captured hologram data to match display requirements, using techniques like interpolation and Fourier transforms to handle differences in pixel pitch between sensors and displays.

Advanced Techniques

To ensure accurate scene reconstruction, the computing device may adjust digital holograms using scaling or resampling techniques. These methods accommodate various pixel arrangements, including regularly or irregularly spaced display elements, ensuring high-quality visual output by aligning sensor data with display capabilities.
