Description
To achieve the angular resolutions required to resolve accretion disks using the intensity interferometry (II) technique, the QUASAR project employs multiple telescopes separated by baselines of up to several tens of kilometers. In this configuration, the conventional approach of delivering signals to a single acquisition system becomes impractical. Instead, precise clock distribution to independent detectors is required. This distributed system introduces timing jitter, both from clock distribution itself and from atmospheric effects that broaden the Hanbury Brown–Twiss (HBT) correlation peak. In this talk, I will present laboratory results on picosecond-level clock synchronization achieved with the White Rabbit system, as well as observational limits on atmosphere-induced HBT peak broadening derived from Sun observations for zero-baseline II setup.
