9 Real-World Variables That Destroy Oscillator Accuracy (And How to Measure Them)
Oscillator drift remains one of the most critical threats to precision timing in high-performance communication systems. In tightly controlled lab environments, performance often appears ideal, but real-world conditions quickly expose hidden weaknesses. Factors like thermal shifts and electromagnetic interference can cause subtle frequency deviations that accumulate over time.

3D metrology for digital twins enables real-time, data-driven system models that mirror physical assets as conditions change.

www.photonicsonline.com/doc/how-high...
How High-Speed Optical Metrology Fuels The Digital Twin Ecosystem
By capturing fast-changing geometries and transient effects, optical systems keep digital twins syncronized under real operating conditions. This measurement speed supports tighter feedback loops between physical processes, simulations, and control systems. As a result, digital twins move from static references to active decision engines grounded in measurable reality.

The Dodgers decided to surrender to an autocrat and the same forces that would have kept Jackie Robinson out of baseball.

I had thoughts on that for @truebluela.bsky.social.
