Engineering Contradiction Analysis
1Measurement precision
If a two-dimensional detector array is used to detect interfered light, then spatial resolution can be improved, but the signal dynamic range is limited which restricts measurement range and accuracy
Solution Approach 1:
The patent combines two different detection systems: a two-dimensional detector array for spatial resolution and a high-rate sensor for extended dynamic range and lower noise. The processor integrates measurements from both detectors, merging their complementary strengths to overcome the limitations of either system alone.
Solution Approach 2:
The system makes the detection system multi-functional by using two different detector types with different capabilities. The two-dimensional detector array provides spatial information while the high-rate sensor provides extended dynamic range and lower noise measurements, making the overall system capable of handling a wider range of signal conditions.
