Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a single image sensor is used to sense interference information, then the device complexity is reduced, but the sensing time increases considerably
Solution Approach 1:
The patent divides the sensing function into multiple independent image sensors, where each sensor captures specific interference information from different spatial regions. This segmentation allows parallel processing of interference patterns, significantly reducing the total sensing time while maintaining measurement accuracy through coordinated operation of multiple sensors.
2Measurement precision
If conventional optical holographic microscopy is used, then the measurement precision is maintained, but the sensing time becomes considerably long
Solution Approach 1:
The patent introduces a temporal dimension to the measurement process by using multiple image sensors to capture interference information simultaneously at different spatial locations. This dimensional expansion from single-point sequential measurement to multi-point parallel measurement enables both high precision and rapid shape recognition without compromising measurement accuracy.
