Optical-Fiber Activation of Observer-Split Source Terms in a Rotating Aluminum Disc

Abstract

We propose an optical-fiber implementation of the Observer-Split source framework for finite rotating systems in extended Aharonov-Bohm electrodynamics. A covariantly conserved current, rewritten in a rotating 3+1 split, produces the observer-adapted source term $I_{\rm split}=N^{-1}D_i(\rho\beta^i)$, which in the weak-field rigid-rotation limit becomes $I_G=\Omega\partial_\phi\rho$. We use an optically gated rotating aluminum disc to create a localized, calibratable induced density, with the optical evanescent/tunneling coefficient acting only as a control gate rather than as a charge density. The resulting source scales as $I_{\rm opt}\simeq\Omega\partial_\phi\rho_{\rm ind,Al}$ and reverses sign under CW/CCW reversal. The proposed demonstrator combines ON/OFF gating, a localized 10--20 degree active sector, uniform-source suppression, material and dummy controls, quantitative null bounds, and independent density calibration. The residual response is parameterized by the experimentally identifiable product $\Lambda_{\rm opt}=\kappa_{\rm opt}\chi_{\rm Al}$, so both positive and null measurements constrain the phenomenology without assuming an uncalibrated force amplitude. Historical rotating magnetic systems, including the Roshchin-Godin report, are used only as benchmarks and not as evidence. The work is a falsifiable protocol for testing anomalous gravitational-response signatures; it reports no anomalous-weight measurement and makes no claim of evidence for a gravitational anomaly or for extended Aharonov-Bohm electrodynamics.
