Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a full simulation of composite light beam propagation is performed, then accuracy of geometric distortions and chromatic aberrations is improved, but computational time increases to several days
Solution Approach 1:
The patent segments the composite electromagnetic beam into multiple individual pixel beams, each processed separately through the propagation model. This allows parallel computation of individual beams while maintaining overall accuracy, significantly reducing total computational time compared to simulating the entire composite beam as a single entity.
Solution Approach 2:
The patent pre-calculates and stores propagation models based on measurement data before actual simulation needs occur. These pre-computed models capture geometric distortions and chromatic aberrations, allowing rapid application during runtime without performing full propagation simulations from scratch, thus reducing computational time while preserving accuracy.
2Device complexity
If existing masking solutions are used to create beam patterns, then device complexity is reduced, but accuracy of geometric distortions and chromatic aberrations deteriorates
Solution Approach 1:
The patent creates simplified copies or representations of the complex propagation physics through pre-computed propagation models derived from measurement data. These models capture the essential geometric distortion and chromatic aberration effects in a computationally efficient form, providing realistic simulation results without requiring full physical accuracy in the simulation engine.
3Productivity
If individual pixel beams are simulated separately and integrated, then computational efficiency is improved, but complexity of model integration increases
Solution Approach 1:
The patent merges the results of individual pixel beam simulations by integrating their contributions to form the complete composite beam pattern. This combining process leverages the pre-computed propagation models to efficiently aggregate individual beam effects, achieving computational efficiency while managing integration complexity through systematic combination of processed pixel data.
Data Source
AI summary
A system for simulation of a composite beam is disclosed. The system can comprise a memory storing executable instructions and one or more processors coupled to the memory to execute the executable instructions. The one or more processors can be configured to generate a representation of the original beam pattern transmitted via a propagation of the composite beam, to invoke a propagation model that represents a distortion for the propagation of the composite beam, and to determine a representation of a distorted beam pattern based on the propagation model and on the representation of the original beam pattern transmitted via the propagation.
