Engineering Contradiction Analysis
1Reliability
If the complete transmission matrix of a medium is computed to correct the disordered signal, then the information conveyed by the initial light signal can be retrieved, but the process becomes time-consuming and requires important computation power
Solution Approach 1:
The patent replaces the computational/mathematical system (transmission matrix calculation) with a physical optical system. By using optical interference between the disordered signal and reference signal, the correction is achieved through physical wave interactions rather than computational algorithms, thereby eliminating the time-consuming computation while maintaining correction accuracy
Solution Approach 2:
The optical system performs self-correction by utilizing the interference between the disordered signal and the reference signal. The system automatically adjusts and optimizes the interference pattern to retrieve the original information without requiring external computational processing or manual intervention in the correction algorithm
2Reliability
If the complete transmission matrix of a medium is computed to correct the disordered signal, then the information conveyed by the initial light signal can be retrieved, but calculation errors may be introduced
Solution Approach 1:
The patent substitutes the computational calculation process with a physical optical measurement process. By using optical interference and detection, the system directly measures the correction parameters through physical wave interactions, avoiding the mathematical calculations that introduce computational errors and precision issues
3Reliability
If prior art techniques are used to correct the effect of a medium on light signal, then correction can be achieved, but the method is complex and expensive
Solution Approach 1:
The patent extracts only the essential elements needed for correction: a reference signal path and an interference detection mechanism. By removing the complex transmission matrix computation and related computational infrastructure, the system achieves correction with minimal components, reducing both device complexity and cost while maintaining correction capability
4Reliability
If prior art techniques are used to correct the effect of a medium on light signal, then correction can be achieved, but it is time-consuming and not industrially applicable
Solution Approach 1:
The patent replaces the slow computational process with a rapid optical process. The interference-based correction occurs in real-time as light waves interact physically, eliminating the sequential computation steps that limit speed, thereby achieving high productivity and industrial applicability while maintaining correction capability
Solution Approach 2:
The optical interference process operates continuously as light signals propagate through the system. The reference signal and disordered signal interfere continuously, providing ongoing correction without the intermittent computation cycles required by prior art methods, thereby maximizing productivity and enabling industrial-scale applications
