Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple light rays are measured sequentially using existing optical spectrum analyzers, then the measurement process can be completed with current hardware, but measurement conditions fluctuate over time causing inaccurate comparison between results
Solution Approach 1:
The patent implements periodic action by performing multiple measurements of different light rays within a single sweep cycle. The controller sequentially switches between multiple light rays and performs measurements at different wavelengths in a periodic manner, ensuring that all measurements are completed before the measurement conditions change. This allows accurate comparison of measurement results while maintaining measurement precision.
Solution Approach 2:
The patent applies continuity of useful action by conducting all measurements within a continuous single sweep operation. The measurement unit continuously measures light intensity at different wavelengths for multiple light rays without interruption, and the controller coordinates the switching and measurement processes to ensure continuous data acquisition. This eliminates gaps between measurements and prevents fluctuations in measurement conditions.
2Productivity
If multiple light rays are measured one-by-one, then measurement resources can be managed with current hardware, but the time difference between measurements causes fluctuations in measurement conditions
Solution Approach 1:
The patent implements dynamics by introducing dynamic switching between multiple light rays during a single sweep. The controller dynamically selects which light ray to measure at each wavelength point based on a predetermined sequence, and the measurement unit dynamically adjusts its measurement target. This dynamic approach allows the system to handle multiple light rays efficiently while completing all measurements within the same sweep cycle, maintaining measurement condition stability.
Solution Approach 2:
The patent applies parameter changes by varying the measured wavelength parameter sequentially for different light rays within a single sweep. The controller changes the wavelength parameter in a coordinated manner while switching between light rays, ensuring that each light ray is measured at all required wavelengths before the sweep ends. This parameter change strategy enables efficient resource utilization while maintaining reliable measurement conditions throughout the process.

AI summary
A non-transitory computer readable medium stores an optical spectrum measurement program to measure, in a single sweep, optical spectra of multiple light rays to be measured. The optical spectrum measurement program is configured to cause a processor to acquire a measurement result of the intensity of a light ray to be measured that is selected one-by-one from among the multiple light rays to be measured, and generate an optical spectrum of each light ray to be measured by associating the light ray to be measured that has been selected during measurement with the acquired measurement result.
