Engineering Contradiction Analysis
1Measurement precision
If de Broglie matterwave interferometry is used to achieve high precision measurements, then measurement precision is improved, but device size increases
Solution Approach 1:
The patent applies dynamics by transitioning from static pulsed atom interferometry to dynamic continuous-wave matterwave oscillation. The matterwave is set into sustained oscillation within a resonant cavity, allowing continuous measurement processes that improve signal-to-noise ratios without requiring larger physical dimensions. This dynamic approach enables the system to accumulate measurement information over multiple oscillation cycles, achieving high precision in a compact form factor.
Solution Approach 2:
The patent implements periodic action through coherent oscillatory matterwave (COMW) generation, where the matterwave oscillates periodically within a resonant cavity formed by mirrors. This periodic oscillation allows the system to perform repeated measurement cycles continuously, improving the signal-to-noise ratio through coherent accumulation of signals over many periods. The periodic nature of the oscillation enables efficient use of the de Broglie wavelength for precision measurement while maintaining a compact device size.
2Measurement precision
If de Broglie wavelengths are used for sensing, then shorter wavelengths provide better precision, but signal-to-noise ratios require larger instruments
Solution Approach 1:
The patent merges the advantages of short de Broglie wavelengths with the signal amplification benefits of resonant oscillation. By combining the matterwave oscillation with a resonant cavity, the system coherently accumulates signals from multiple oscillation cycles, effectively merging the precision capability of short wavelengths with the signal-to-noise improvement of repeated measurements. This merging allows the system to achieve both high precision and reliable signal detection in a compact configuration.
Solution Approach 2:
The patent achieves continuity of useful action through continuous-wave matterwave oscillation, where the matterwave continuously oscillates within the resonant cavity rather than being pulsed. This continuous operation allows for uninterrupted signal accumulation and measurement, improving the signal-to-noise ratio by continuously utilizing the short de Broglie wavelength for precision measurement. The continuous oscillation ensures that the sensing action is sustained without interruption, enhancing both precision and reliability.
