Abstract
We show how an observer could measure the non -local holonomy variables that
parametrise the flat Lorentzian 3d manifolds arising as spacetimes in (2+1)-gravity.
We consider an observer who emits lightray s that return to him at a later time
and performs several realistic measurements associated with such retur ning ligh-
trays: the eigentime elapsed between the emission of the lightrays and their return,
the directions into which the light is emitted and fr om which it returns an d the
frequency shift between the emitted and returning lightray. We show how the
holonomy variables and hence the full geometry of these manifolds can be recon-
structed from these measurements in finite eigentime.
