Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a photon-number-resolving detector is used to measure weak light characteristics, then photon number resolution capability is achieved, but the application scope in the measurement field remains limited
Solution Approach 1:
The patent integrates multiple measurement functions into a single system by combining a photon-number-resolving detector with a sample holder that can perform chemical reactions, temperature adjustment, and mechanical state control. This multi-functional integration allows the detector to measure not only photon numbers but also chemical composition, reaction processes, temperature, and mechanical states, thereby expanding its application scope while maintaining photon number resolution capability
2Device complexity
If the photon-number-resolving detector measures only transmitted light, then the detection principle is simple, but the measurement information is insufficient
Solution Approach 1:
The patent divides the light measurement into three distinct segments: transmitted light, reflected light, and scattered light. Each segment provides different measurement information about the sample. By separately detecting these three light components using the photon-number-resolving detector, the system obtains comprehensive measurement information including chemical composition, reaction processes, temperature, and mechanical states without significantly increasing detection principle complexity
