Figure | ST-Comb information transmission under outdoor and phase-screen-equivalent turbulence. a, Complete workflow from digital encoding and ST-Comb modulation to propagation, Guide-Star reconstruction and ST-Net decoding. b and c, Local field fidelity decreases with increasing turbulence, while the global spatiotemporal-spectral fingerprint remains recoverable. d and e, Real 100 m outdoor free-space transmission at the Shanghai Astronomical Observatory. f, Phase-screen-equivalent turbulence tests corresponding to 100 m, 1 km and 10 km propagation; the longer distances are equivalent tests rather than physical outdoor links.
