Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple imaging cameras and lenses are used to test and calibrate image quality of field-of-view displays with prescription lenses, then measurement precision is improved, but device complexity increases and manufacturing cost increases
