Holographic Energy Calibration for 4D Plenoptic Waveguide Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to create a seamless and high-resolution energy surface for holographic displays that can effectively stimulate human sensory receptors, lacking the ability to provide a compelling interactive virtual world experience akin to the Holodeck concept, due to limitations in resolution, data throughput, and manufacturing feasibility.
Innovation Solution
The method involves calibrating energy relay elements for higher transport efficiency in a longitudinal orientation and using energy waveguide arrays to direct energy along uninhibited propagation paths, creating a calibrated four-dimensional plenoptic function that maps energy attributes and angular directions, enabling bidirectional energy propagation and seamless surface configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional energy relay elements and waveguide arrays are used, then device complexity is reduced, but energy propagation efficiency and resolution deteriorate
Solution Approach 1:
The patent applies preliminary action by performing calibration procedures before the holographic energy directing system is deployed for its intended purpose. The system pre-determines the mapping between energy locations on the input surface and angular directions of propagation through waveguide elements, storing this calibration data for later use. This preliminary calibration enables high energy propagation efficiency during operation without requiring complex real-time adjustments.
Solution Approach 2:
The system implements self-service through automated calibration processes that characterize the energy relay elements and waveguide arrays without requiring manual intervention. The calibration system automatically measures energy propagation characteristics, computes mapping relationships, and stores calibration data, allowing the system to self-characterize and optimize its performance.
2Manufacturing precision
If high-resolution energy surface is created for holographic displays, then image quality improves, but manufacturing feasibility deteriorates
Solution Approach 1:
The patent applies copying by creating a calibrated model or map of the energy propagation characteristics rather than physically adjusting each element. The calibration process generates a digital representation of the mapping between energy locations and propagation angles, which can be stored and reused. This copying approach enables high-resolution energy surfaces to be manufactured using standard processes, with precision achieved through computational calibration rather than stringent manufacturing tolerances.
3Measurement precision
If calibration data is collected from multiple energy locations and angles, then mapping precision improves, but data collection time increases
Solution Approach 1:
The patent applies segmentation by dividing the calibration process into distinct stages: (1) characterizing energy relay elements by collecting data from multiple energy locations, (2) characterizing waveguide elements by measuring angular propagation directions, and (3) combining these characterizations to create the complete mapping. This segmented approach allows systematic data collection that improves mapping precision while managing calibration time through structured procedures.

AI summary
Holographic energy directing systems may include a waveguide array and a relay element. Disclosed calibration approaches allows for mapping of energy locations and mapping of energy locations to angular direction of energy as defined in a four-dimensional plenoptic system. Distortions due to the waveguide array and relay element may also be compensated.
