HOLOGRAPHIC DISPLAY APPARATUS FOR PROVIDING EXPANDED VIEWING WINDOW - A simplified explanation of the abstract
This abstract first appeared for US patent application 18369039 titled 'HOLOGRAPHIC DISPLAY APPARATUS FOR PROVIDING EXPANDED VIEWING WINDOW
Simplified Explanation
The holographic display apparatus described in the patent application is designed to provide an expanded viewing window when reproducing holographic images using an off-axis technique. It consists of a spatial light modulator with two-dimensional pixel arrangement and an aperture enlargement film that enlarges the beam diameter of the light beam emitted from each pixel of the spatial light modulator. The enlarged beam diameter is greater than the width of the aperture of each pixel.
- The holographic display apparatus uses an off-axis technique to reproduce holographic images.
- It includes a spatial light modulator with a two-dimensional pixel arrangement.
- An aperture enlargement film is used to enlarge the beam diameter of the light beam emitted from each pixel.
- The enlarged beam diameter is greater than the width of the aperture of each pixel.
Potential Applications:
- Holographic displays for entertainment purposes, such as gaming or virtual reality.
- Medical imaging and visualization, allowing for more detailed and immersive representations of anatomical structures.
- Architectural and engineering design, enabling realistic 3D visualizations of buildings and structures.
- Advertising and marketing, creating eye-catching and interactive holographic displays for product promotion.
Problems Solved:
- Limited viewing window in traditional holographic displays.
- Off-axis technique allows for an expanded viewing window, enhancing the user experience.
- Enlarging the beam diameter of each pixel's light beam improves the quality and clarity of the holographic image.
Benefits:
- Expanded viewing window provides a larger and more immersive holographic experience.
- Improved image quality and clarity due to the enlarged beam diameter.
- Enhanced user experience in various applications, from entertainment to medical imaging.
- Potential for more realistic and interactive advertising and marketing displays.
Original Abstract Submitted
Provided is a holographic display apparatus capable of providing an expanded viewing window when reproducing a holographic image via an off-axis technique. The holographic display apparatus includes a spatial light modulator comprising a plurality of pixels arranged two-dimensionally; and an aperture enlargement film configured to enlarge a beam diameter of a light beam coming from each of the plurality of pixels of the spatial light modulator. The beam diameter of each light beam enlarged by the aperture enlargement film may be greater than the width of an aperture of each pixel of the spatial light modulator.
