Achieved consistent optical transmission and stimulation with high cancellation quality (CMRR 133 dB).
The setup provides theoretical detectability limits for biological tissues.

Abstract

This article explores the hypothesis that a hollow-core optical fiber with Diamond-Like Carbon (DLC) nanocarbon coating could restore nerve conduction across a cervical C5-C6 lesion, unifying three functions in a single device: (1) interferometric detection of axonal swelling (1-5 nm, Tasaki 1982) via in-vivo DAS, (2) optical transmission at 750 nm with in-situ photoacoustic calibration, and (3) reconversion into distal stimulation by FUS or photoacoustics. The Tri-Core three-phase cancellation at 120 degrees (CMRR 133 dB verified in acoustics) guarantees zero thermal dissipation. The kG framework extended to biological tissues provides theoretical detectability limits. Contact: b. gasque@icloud. com
