We report a sensitive study of measuring photon polarisation in with an integrated luminosity of = 1 ab at a center-of-mass energy of 3.773 GeV at a future Super Tau Charm Facility. More than 61,000 signals of are expected. Based on a fast simulation software package, the statistical sensitivity for the ratio of up-down asymmetry is estimated to be by performing a two-dimensional angular analysis in . Combining with measurements of up-down asymmetry in , the photon polarisation in can be determined model-independently.
